1500 families with 2 children were selected randomly and the following data were recorded:


If a family is chosen at random, compute the probability that it has:
(i)No girl  
(ii)  1 girl    
(iii)  2 girls
(iv)at most one girl   

Text Solution

Verified by Experts

Total number of families =`475+814+211=1500`
(i)P(no girl)=`211/1500`
(ii) P(1 girl) = `814/1500 = 407/750`
(iii) P(2 girls) = `475/1500=19/60`
(iv)P(at most one girl)=`(211+814)/1500`
`=1025/1500`
