Question

From a group of 3 girls and 2 boys , two children are selected at random.find the probability such that at least one girl is selected?

Answer 1

total outcomes= 5
possibility of one girl= 3/5

Answer 2

Answer:

Step-by-step explanation:

Let G1, G2 and G3 be the girls

And B1 and B2 be the boys.

Since two children at random are to be selected,the possible outcomes are::

G1 G2

G2 G3

G1 G3

G1 B1

G1 B2

G2 B1

G2 B2

G3 B1

G3 B2

B1 B2

No.of outcomes having at least one girl(one or more than one girl)=9

Total no. of outcomes=10

So, required probability=9/10
