In Class X, there are 40 students: 25 girls and 15 boys. The teacher randomly draws one name card from the bag. What is the probability that the card will have:
(i) A girl’s name?
(ii) A boy’s name?
Solution:
There are 40 students in total.
(i) The number of girls is 25.
So, the probability of drawing a girl’s name is:
P(girl) = 25/40 = 5/8
(ii) The number of boys is 15.
So, the probability of drawing a boy’s name is:
P(boy)=15/40 = 3/8
