Answer 1

Answer:

2/3

Step-by-step explanation:

outcomes have at least one boy {BBB,BBG,BGG,BGB,GBB,GBG,GGB,GGG}.

The important question is why did we chose this set as our basis and why is the probability of each of these equal.

so probability

= no of possible out comes/total no of out comes
