Step-by-step explanation:

Probability that the pianist will be a boy and the alternate will be a girl?
Solution:
Here we have to make 2 choices.
1st choice has to be boy (pianist) and 2nd choice has to be girl (alternate).
Formula for probability of an event E is given as:

Total number of cases = Total number of students i.e. 5
So, is:
For , number of favorable cases are 3 (total number of girls).
Now, one boy is already chosen as pianist so Total number of cases = Total number of students left i.e. (5 - 1) = 4
So, the required probability is:
