Question

A-C please

If a couple were planning to have three children, the sample space summarizing the gender outcomes would be: bbb, bbg, bgb, bgg, gbb, gbg, ggb, ggg a. Construct a similar sample space for the possible hair color outcomes (using b for brown-haired and r for red-headed) of two children b. Assuming that the outcomes listed in part (a) were equally likely, find the probability of getting two brown-haired children. c. Find the probability of getting exactly one brown-haired child and one red-headed child. a. What is the sample space? (Use a comma to separate answers as needed)

Explanation / Answer

a) Sample space = bb, br, rb, bb

b) Number of outcomes = 4

So, P(getting two brown haired children) = P(bb) = 1/4 = 0.25

c) P(one brown haired child and one red-headed child) = P(br or rb)

= 2/4 = 0.5
