0 votes 0 votes Correct - AS She has a boy P(She has two boys/ she is invited to dinner) 1/4 | 3/4 = 1/3 Incorrect - (but again i think she should have 1/2 as sample space should be like this (bb,gb). only one is atleast son so why it shouldn't be 1/2 answer?) bankeshk answered Jul 20, 2019 bankeshk comment Share Follow See all 0 reply Please log in or register to add a comment.
