Answer» 3 children given. let ‘s b denote boy and g denote girl. bbb, bbg, bgb, gbb, ggg, ggb, gbg, bgg total 8 possibilities. (1) Probability of no girl Possibility = 1(bbb) So, probability = 1/8 (2) Probability of one girlPossibilities = 3 (bbg, bgb, gbb) So, probability = 3/8 (3) Probability of two girlsPossibilities = 2 (bgg, ggb) So, probability = 2/8 = 1/4 (4) Probability of three girlsPossibilities = 1 (ggg) So, probability = 1/8 Therefore, probability = 1/4 is true for only one condition when there are two girls.

Answer»

3 children given. let ‘s b denote boy and g denote girl.

bbb, bbg, bgb, gbb, ggg, ggb, gbg, bgg total 8 possibilities.

(1) Probability of no girl Possibility = 1(bbb) So, probability = 1/8

(2) Probability of one girlPossibilities = 3 (bbg, bgb, gbb) So, probability = 3/8

(3) Probability of two girlsPossibilities = 2 (bgg, ggb) So, probability = 2/8 = 1/4

(4) Probability of three girlsPossibilities = 1 (ggg) So, probability = 1/8

Therefore, probability = 1/4 is true for only one condition when there are two girls.
