There are 55 black balls and 88 red balls in an urn. If 44 balls are drawn without replacement, what is the probability that no more than 11 black ball is drawn
Answer:
[tex]Probability = \frac{70}{143}[/tex]
Step-by-step explanation:
Given
[tex]Black = 5[/tex]
[tex]Red = 8[/tex]
[tex]Total = 13[/tex]
To solve the required probability, we need to determine the number of available selections:
There are two possible scenarios;
1: All 4 selections are red.
2. 1 selection is black, while 3 others are red
Scenario 1: All Red
[tex]^8C_4 = \frac{8!}{(8-4)!4!}[/tex]
[tex]^8C_4 = \frac{8!}{4!4!}[/tex]
[tex]^8C_4 = \frac{8*7*6*5*4!}{4!4!}[/tex]
[tex]^8C_4 = \frac{8*7*6*5}{4!}[/tex]
[tex]^8C_4 = \frac{8*7*6*5}{4*3*2*1}[/tex]
[tex]^8C_4 = \frac{1680}{24}[/tex]
[tex]^8C_4 = 70[/tex]
Scenario 2: 1 Black, 3 Red
Selecting Black:
[tex]^5C_1 = \frac{5!}{(5-1)!1!}[/tex]
[tex]^5C_1 = \frac{5!}{4!1!}[/tex]
[tex]^5C_1 = \frac{5*4!}{4!*1}[/tex]
[tex]^5C_1 = 5[/tex]
Selecting Red:
[tex]^8C_3 = \frac{8!}{(8-3)!3!}[/tex]
[tex]^8C_3 = \frac{8!}{5!3!}[/tex]
[tex]^8C_3 = \frac{8*7*6*5!}{5!3*2*1}[/tex]
[tex]^8C_3 = \frac{8*7*6}{6}[/tex]
[tex]^8C_3 = 8*7[/tex]
[tex]^8C_3 = 56[/tex]
Number of Selection = 5 * 56
[tex]Selection = 280[/tex]
Total Available Selection is calculated as thus:
[tex]Available\ Selection = 70 + 280[/tex]
[tex]Available\ Selection= 350[/tex]
Next, is to calculate the number of possible selections:
i.e 4 balls out of 13
This is calculated as:
[tex]^{13}C_4 = \frac{13!}{(13-4)!4!}[/tex]
[tex]^{13}C_4 = \frac{13!}{9!4!}[/tex]
[tex]^{13}C_4 = \frac{13 * 12 * 11 * 10 * 9!}{9!4*3*2*1}[/tex]
[tex]^{13}C_4 = \frac{13 * 12 * 11 * 10}{4*3*2*1}[/tex]
[tex]^{13}C_4 = \frac{17160}{24}[/tex]
[tex]^{13}C_4 = 715[/tex]
[tex]Probability = \frac{Available\ Selection}{Possible\ Selection}[/tex]
[tex]Probability = \frac{350}{715}[/tex]
[tex]Probability = \frac{70}{143}[/tex]
A box office sells balcony seats, ground-level seats, and VIP passes for shows on tour. The table shows the numbers of each type of ticket sold and the revenues for the first three shows of a tour. What is the price of each type of ticket?
Answer:
The price of one Balcony seat = $50
The price of one Ground level seat = $90
The price of one VIP seat = $180
Step-by-step explanation:
Let the price of one Balcony seat = $[tex]x[/tex]
Let the price of one Ground level seat = $[tex]y[/tex]
Let the price of one VIP seat = $[tex]z[/tex]
As per the given table:
[tex]135x+280y+29z=37170 ....... (1)\\150x+270y+58z=42240 ....... (2)\\130x+265y+29z=35570 ....... (3)[/tex]
Multiplying (1) with 2 and subtracting (2) from it:
[tex]120x+290y=32100 \\12x+29y=3210..... (4)[/tex]
Subtracting (3) from (1):
[tex]5x+15y=1600\\x+3y=320 ....... (5)[/tex]
Multiply equation (5) with 12 and subtracting (4) from it:
[tex]7y=630\\\Rightarrow y =\bold{90}[/tex]
By equation (5), putting value of [tex]y[/tex]:
[tex]x=\bold{50}[/tex]
By equation (1), putting the values of [tex]x, y:[/tex]
[tex]135\times 50+280\times 90+29z=37170\\\Rightarrow 29z=37170-31950\\\Rightarrow 29z=5220\\\Rightarrow z =\bold{180}[/tex]
Therefore, the answers are:
The price of one Balcony seat = $50
The price of one Ground level seat = $90
The price of one VIP seat = $180
PLEASE ANSWER ASAP!!! Find the discriminant of the following function. Then identify how many solutions and the type of solutions there will be.
f(x)=3x^2-7x+5
Answer:
No solutionStep-by-step explanation:
Given function
f(x) = 3x^2 - 7x + 5Zeros of the function
3x^2 - 7x + 5 = 0D = √(b^2 - 4ac) = √(49 - 60) = √-11There is no solution as the discriminant is negative
It means the graph of this function doesn't intersect with x axis and is above it

A box of books has 12 fiction and 14 nonfiction books in it. Determine the odds in favor of you selecting a fiction book from the box.
Answer:
Odds in favor(Fiction book) = 6 / 13
Step-by-step explanation:
Given:
Number of fiction books = 12
Number of non-fiction books = 14
Find:
Odds in favor(Fiction book)
Computation:
Odds in favor(Fiction book) = Number of fiction books / Total books
Odds in favor(Fiction book) = 12 / (12+14)
Odds in favor(Fiction book) = 12 / 26
Odds in favor(Fiction book) = 6 / 13

y-3=2(x+1) please please help
Answer:
y=2x+5
Step-by-step explanation:
distribute 2 to x and 1, do this by multiplying each.
you should get y-3=2x+2.
then you have to move the -3 from the left to the right. but when you do this you have to change the -3 to a positive 3. then combine 3 and 2.
you then get the answer, y=2x+5.
