Question

There is 32 students in class.8 boys out of 20 wear cap and 8 girls out of 12 wear spectacles find the probability that the student is boy who wears cap or girls who doesn't wear spectacles ​

Answer 1

Boy = 40%

Girl = 66.6%

Explanation:

1) Work out probability that student is a boy who wears cap

8 boys out of 20 wears a cap so to find the probability we have to do 8 divided by 20

• 8 ÷ 20 = 0.4
• 0.4 × 100 = 40%

2) Work out probability for girls who doesn't wear spectacles

To find the probability of girls who doesn't wear spectacles we have to do 8 divided by 12

• 8 ÷ 12 = 0.666...(recurring)
• 0.666...(recurring) × 100 = 66.6%

Hope this helps, have a lovely day! :)
