Class consists of 21 boys and 9 girls. A student is to be selected for social work. Find the probability that(i) a girl is selected(ii) a boy is selected​

Answer»

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.

HOPE THIS ANSWERS THE QUESTION! :)
