okay so i will use B for boy n G for Girl.There are 3 children
so possibilities are-
BBB,BBG,BGG,GGG,GBG
favourable outcomes(atleast one boy)=BBB,BBG,BGG,GBG,
considering this:
P(E)=no.of favorable outcomes/total no. of outcome
=4/5
so possibilities are-
BBB,BBG,BGG,GGG,GBG
favourable outcomes(atleast one boy)=BBB,BBG,BGG,GBG,
considering this:
P(E)=no.of favorable outcomes/total no. of outcome
=4/5
yashucool:
BBG and BGB are same outcomes
