Question

Your teacher is selecting class partners by drawing names out of a bag. There are 12 girl's names and 10 boy's names. What is the probability that she selects a boy's name followed by a girl's name (without replacement)?
A) 20/77

B) 30/121

Answer 1

The answer would be A)20/77.
The reason is that without replacement it would go (10/22)*(12/21)=0.2597
You can do the easy route I did then do (20/77) which would also give you 0.2597.
