The ratio of girls to boys in this case would be 10:1
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%
2/5 = 4/10 1/2 = 5/10 2/5 < 1/2, so there are more boys than girls
18 boys in a class of 10+18 = 28 represents 100*18/28 = 64.29% okok thank you
