Answer:
(i) 3/10
(ii) 9/10
Step-by-step explanation:
There are total 30 students in the class!
No. of girls= 9
No. of boys= 21
So to find the probability of a girl picked at random, we should divide 9 by 30 which is equal to 3/10 (on simplifying) and to find the probability of a boy picked at random, we should divide 21 by 30 which is equal to 9/10.
