Question

there are three children in family find the probability that there is at most one girl in the family​

Answer 1

Answer:

1/3 is the probability

Step-by-step explanation:

There are 3 children totally.

Total favourable outcomes = 3

Favourable outcomes = 1 (since we expect at most 1 girl)

Probability = Favourable outcomes/Total Outcomes.

P = 1/3

Therefore, Probability of getting 1 girl is 1/3.

Answer 2

    Solution   :

➣ given = 3 children

Let (b) denote boy and (g) denote girl.

➣ Total no. of outcomes =bbb, bbg,

bgb, gbb , ggg , ggb , gbg , bgg

= 8 outcomes

➣ Now, we want only one girl child.

➣ List out the possibilities with one girl child from the total possibilities

= bbg, bgb, gbb

= 3

➣Probability of ( one girl in the family ) = 3 / 8 ✅✅✅
