To the right are the outcomes that are possible when a couple has three children. Refer to that list, and find the probability of each event. a. Among three children, there is exactly 1 boy. b. Among three children, there are exactly 2 girls. c. Among three children, there are exactly 3 boys. a. What is the probability of exactly 1 boy out of three children? [Type an integer or a simplified fraction.) b. What is the probability of exactly 2 girls out of tee children? [](Type an integer or a simplified fraction.) c. What is the probability of exactly 3 boys out of tee children? []Type an integer or a simplified fraction.)

Solution

Assuming all the outcomes are equally likely,

P(1 boy out of 3 children)=3/8

P(2 girls out of 3 children)=P(1 boy out of 3 children)=3/8

P(all three are boys)=1/8
