Question

In a class, there are 18 girls and 16 boys. The class teacher wants to choose one pupil for class monitor. What she does, she writes the name of each pupil on a card and puts them into a basket and mixes thoroughly. A child is asked to pick one card from the basket. What is the probability that the name written on the card is the name of a boy?

Solution

Total no. of possible outcomes = 34 (18 girls, 16 boys)

E ⟶ event of getting boy name

No. of favorable outcomes = 16 (16 boys)

Probability, P(E) =`"No.of favorable outcomes"/"Total no.of possible outcomes"`

P(E) =16/34 =8/17

  Is there an error in this question or solution?
