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.
1) $$\dfrac{8}{17}$$ 2) $$\dfrac{5}{6}$$ 3) $$\dfrac{15}{16}$$ 4) None of these
Total number of students $$= 18 + 16 = 34$$ Total number of girls $$= 18$$ Total number of boys $$= 16$$ P(Boy) $$= \displaystyle \frac{16}{34} = \frac{8}{17}$$
