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%
5/16 6 Boys 10 Girls Half the girls wear glasses. Half of 10 is 5. 5 Girls wear glasses. Probability=outcome wanted/total 5 girls wear glasses/16 kids in class or 5/16 Message me with any questions.
Assuming the choices are made randomly and that the chosen people are not returned to the class, the probability is 77/690 = 0.1116 approx.
7 boys
If the ratio of boys to girls is 12 to 3, then the total ratio is 12 + 3 = 15. To find how many girls are in the class, we divide the number of girls by the total ratio, 24 / 15 = 1.6. This means there are approximately 1.6 girls in the class. However, since we can't have a fraction of a girl, we can conclude that there are 2 girls in the class.
Probability that a girl is chosen = 23/45 = .511 So, the probability that a boy is chosen = 1 - .511 = .489
Upper Class girls where chosen, by there family, only the richest could decide.
They were not chosen they were born into the position.
The probability is 15/25 = 3/5
The probability is 15/25 = 3/5
12/27 reduces to 4/9 numerator = the number of acceptable outcomes denominator = total number of outcomes (12 boys + 15 girls)
Husbands were chosen by parents.
The probability is the number of girls divided by the number of students, so 12/22, or 6/11
If the person is picked at random, the the probability is 3/7.
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%
He probably thinks you are beautiful,as all girls are.
Usually by association with people of the same class system. They are invited to functions, parties and other social events frequented by people of similar upbringings.
