Answer:

1800

Step-by-step explanation:

(1/2)/100 of x = 9

1/2*1/100 of x = 9

1/200 of x = 9  

x/200 of x = 9

x = 9*200

x = 1800

) Suppose that a subset of five balls will be randomly selected from an urn containing amber, blue, and green balls. (a) If the
vazorg [7]

Answer:

0.0023 = 0.23% probability that all 5 balls selected will be the same color

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

The order in which the balls are selected is not important, which means that the combinations formula is used to solve this question.

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)!}

Desired outcomes:

Either 5 amber from a set of 6, or 5 blue from a set of 5. So

D = C_{6,5} + C_{5,5} = \frac{6!}{5!1!} + \frac{5!}{5!0!} = 6 + 1 = 7

Total outcomes:

5 balls selected from a set of 6 + 5 + 4 = 15. So

T = C_{15,5} = \frac{15!}{5!10!} = 3003

Probability:

p = \frac{D}{T} = \frac{7}{3003} = 0.0023

0.0023 = 0.23% probability that all 5 balls selected will be the same color
