2-77. Janelle's aunt and uncle had three children. Two of them were girls. Since girls and be boys are equally likely, Janelle thought that the chance of having two or more must be 50%. Janelle's brother thought the chance of having so many girls had to less than 50%. girls What do you think? Make a conjecture about the probability of having two or three girls in a family of three siblings. a. b. Do a computer simulation to estimate the probability of having two or three girls in a family of three siblings. Your teacher will show you how to simulate a family of three siblings
