Answer:

Step-by-step explanation:

Given that a claw game holds pink, red, green, and blue stuffed toys. The machine randomly picks up a toy but then drops it back into the collection. The results from 60 attempted toy selections are shown in the table

Toy color Times picked

pink 9

red 30

green 3

blue 18

Total 60

Relative freq of red toy = no of red toys/total = 30/60 =0.50

Green toy = 3/60 = 0.05

It is likely that the machine has the greatest number ____red_____of toys. It is likely that the machine has the least number ____green___of toys.

<u>ANSWER: </u>

The value of x after evaluating the given equation x + 6 - 5 = 8 - 2 is 5.

<u>SOLUTION: </u>

Given, equation in one variable is x + 6 – 5 = 8 – 2

And, now, we have to find the value of the variable x in the equation by solving the given equation.

So, let us solve the given equation for x.

Then, x + 6 – 5 = 8 – 2

x = 8 – 2 – (6 – 5) [sending all the numerical terms on left side to the right side.

x = 8 – 2 – 6 + 5

x = 8 + 5 – 2 – 6

x = 13 – 8 = 5

Hence, the value of x after evaluating the given equation is 5.

A TV studio has brought in 8 boy kittens and 10 girl kittens for a cat food commercial.

Answer:

0.323 = 32.3% probability that the director chooses 3 boy kittens and 5 girl kittens.

Step-by-step explanation:

The kittens are chosen without replacement, which means that the hypergeometric distribution is used to solve this question.

Hypergeometric distribution:

The probability of x sucesses is given by the following formula:

$P(X = x) = h(x,N,n,k) = \frac{C_{k,x}*C_{N-k,n-x}}{C_{N,n}}$

In which:

x is the number of sucesses.

N is the size of the population.

n is the size of the sample.

k is the total number of desired outcomes.

Combinations formula:

$C_{n,x}$ is the number of different combinations of x objects from a set of n elements, given by the following formula.

$C_{n,x} = \frac{n!}{x!(n-x)!}$

A TV studio has brought in 8 boy kittens and 10 girl kittens for a cat food commercial.

This means that $N = 8 + 10 = 18$

We want 3 boys, so $k = 8$

The director is going to choose 8 of these kittens at random to be in the commercial.

This means that $n = 8$

What is the probability that the director chooses 3 boy kittens and 5 girl kittens?

This is P(X = 3).

$P(X = x) = h(x,N,n,k) = \frac{C_{k,x}*C_{N-k,n-x}}{C_{N,n}}$

$P(X = 3) = h(3,18,8,8) = \frac{C_{8,3}*C_{10,5}}{C_{18,8}} = 0.323$

0.323 = 32.3% probability that the director chooses 3 boy kittens and 5 girl kittens.
