im thinking its 2 of of 20 ( 2/20)
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%
I am not going to help you cheat in math class!!!!!!!!!!!!!
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.
1/35
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.
2/5
If the choice is unbiased, the change is 14/(10+14). If the chooser prefers choosing boys, the probability is 0.
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 probability is always a fraction except when it is 0 or 1. If a probability = 1 then it will definitely happen. If the probability is 0 then it will not happen. If you toss a fair coin the probability of heads is 1/2, and the probability of tails is 1/2. These fractions are representations of the probabilities. Not all fractions are representative of probabilities. Fractions can be used to represent a portion of a whole. Like what portion of a class is boys, and what portion is girls: If there are 8 boys and 7 girls, then the 8/15 of the class is boys, and 7/15 of the class is girls.
The probability is the number of girls divided by the number of students, so 12/22, or 6/11
17 out of 27, or about 0.6296.

a 33.3333333333333333333% chance because there are 15 people in the class.
The probability is 15/25 = 3/5
It is 15/38.
If the person is picked at random, the the probability is 3/7.
Prob = 3/45 = 1/15Prob = 3/45 = 1/15Prob = 3/45 = 1/15Prob = 3/45 = 1/15
