Question

A bucket contains one green block, one red block, and two yellow blocks. You choose one block from the bucket.

a. Find the theoretical probability that you will choose each color.

P(green) = P(yellow) = P(red) =

b. Find the sum of the probabilities in part (a)

c. What is the probability that you will not choose a red block? Explain how you found your answer.

d. What is the sum of the probability of choosing a red block and the probability of not choosing a red block?

Answer 1

p(green) = 1/4 p(yellow) = 2/4 p(red) = 1/4
the sum of probabilities is 1
p(not red) = 2/4, 1 - probability of getting red
the sum is 1
