work. Find the probability that (i) a girl is selected (ii) a boy is selected
​

Answer 1

Answer:

girl 3/10 boy9/10

Step-by-step explanation:

There are total 30 students in the class! 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.
