12/21 or 4/7
The probability of choosing 2 girls at random from group of 25 students of which10 are girls and 15 are boys is:P( 2 girls) = (10/25)∙(9/24) = 3/20 = 0.15 = 15%

1/35
this is 15/91
80 boys and 30 girls
The probability of choosing 2 girls at random from group of 25 students of which10 are girls and 15 are boys is:P( 2 girls) = (10/25)∙(9/24) = 3/20 = 0.15 = 15%
The ratio of girls to total students is 15:25, or 3:5. Three out of five students are girls so there would be a 60% probability that a girl would be chosen; a 2 out of 5 chance, or 40% probability that a boy would be chosen.
The probability is 15/25 = 3/5
13 out of 20
The probability is the number of girls divided by the number of students, so 12/22, or 6/11

The probability is 15/25 = 3/5
1/35
this is 15/91
1/12 =0.08333... ≈ 8.3%
If there are 12 boys and 6 girls, the total number of students would be 18. You are looking for the probability of selecting a girl from the class: 6/18 Just reduce the fraction to its lowest form 6/18 = 2/6 = 1/3 Your answer would be 1/3.
