Answer:

A. 2/5

B. 1/10

Step-by-step explanation:

Firstly, we want to calculate the probability that the chosen child is a girl.

To calculate this probability, we need to know the number of girls .

This is accessible from the table. There are a total of 8 girls.

Thus the probability of a girl being chosen is simply equal to the number of girls/ total number of children = 8/20 = 2/5

The probability that the chosen girl is left handed.

The number of left handed girls we have is

only 2. Thus the probability of choosing a left handed girl will be 2/20 = 1/10
