Question

Mr. Hammond cut out some colored stars from a stencil to decorate his bulletin board. He put them in a bag and randomly selects them as he decorates. The stars shown are what is left after he is about halfway finished. What is the probability the next star he randomly selects will NOT be blue?

Answer 1

Answer:the probability is a fifty- fifty chance

Explanation:

First the colored stars could be different colors including blue so you may never know if he is going to pull out a blue star or different color star.

But if you use the Formula for the probability of A and B (independent events): p(A and B) = p(A) * p(B). If the probability of one event doesn't affect the other, you have an independent event. All you do is multiply the probability of one by the probability of another.or:

The probability of an event=(the number of favorable outcomes) /

(total number of possible outcomes)

in equation form-P(A)=n(E)/n(S)

P(A)< 1

or

if the probability of occurring an event is P(A) then the probability of not occurring an event is

P(A')= 1-P(A)
