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 eye color outcomes (using b for blue-eyed and g for green-eyed) of two children. b. Assuming that the outcomes listed in part (a) were equally likely, find the probability of getting two green-eyed children. c. Find the probability of getting exactly one blue-eyed child and one green-eyed child.
