Question

Here is some information about a group of 20 children. A change ls chosen at random from a group.

A) what is the probability that the chosen child is a girl? Give your answer as a fraction.

B) what is the probability that the chosen child is a left handed girl? Give your answer as a fraction.

Answer 1

Answer:2/20

Step-by-step explanation: work out the answer

Answer 2

A. 2/5

B. 1/10

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
