Two boys and three girls are auditioning to play the piano for a school production. Two students will be chosen, one as the pian
finlep [7]

Answer:

30% is the correct answer.

Step-by-step explanation:

Total number of boys = 2

Total number of girls = 3

Total number of students = 5

To find:

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).

\bold{\text{Required probability }= P(\text{boy as pianist first}) \times P(\text{girl as alternate})}

Formula for probability of an event E is given as:

P(E) = \dfrac{\text{Number of favorable cases}}{\text {Total number of cases}}

For P(\text{boy as pianist}), number of favorable cases are 2 (total number of boys).

Total number of cases = Total number of students i.e. 5

So, P(\text{boy as pianist}) is:

P(\text{boy as pianist}) = \dfrac{2}{5}

For P(\text{girl as alternate}), 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

P(\text{girl as alternate}) = \dfrac{3}{4}

So, the required probability is:

\text{Required probability } = \dfrac{2}{5}\times \dfrac{3}{4} = \dfrac{3}{10} = \bold{30\%}
