The experimental probability that 4 of 4 children in a family are girls obtained using the formula for experimental probability is; 1/10 = 10%
Experimental probability = 10%
The number of children in the family = 4
The number of coins used in the experiment = 4
The outcomes; Heads, H, represents a boy and tails, T, represent a girl
The total number of outcomes = 20 coin tosses
The experimental probability that 4 of 4 children in a family are girls
The number of outcomes where 4 of 4 children are girls, which is TTTT are 2, therefore;
The experimental probability that 4 of 4 children in a family are girls therefore is; 2/20 = 1/10
1/10 = 10%
The experimental probability is 10%
