What is the probability a boy is chosen if their are 26 kids and 10 are girls?
If 10 out of 26 are girls, then the probability of randomly choosing a boy is 16 out of 26, or 8 out of 13, or about 0.6154.
What is probability 2 girls are chosen if 10 students are girls and 15 are boys?
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%
In a second grade class containing 13 girls and 9 boys 2 students are selected at random to give out the math papers. What is the probability that the second student chosen is a boy given that the fir?
To find the probability that the second student chosen is a boy given that the first student chosen is a boy, we first note that there are 22 students total (13 girls and 9 boys). If the first student chosen is a boy, there will then be 8 boys and 13 girls remaining, making a total of 21 students left. Therefore, the probability that the second student is a boy is the number of remaining boys (8) divided by the total remaining students (21), which gives us a probability of ( \frac{8}{21} ).
A class of 14 boys and 11 girls. What is the probability of selecting a girl 1st and then a girl 2nd and then a boy third.?
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.
What is the probability that the 6 child family has exactly two girls?
The probability is 2 - 6
If there are 45 students in a biology class and 23 are girls what is the probability that a student chosen at random will be a boy?
Probability that a girl is chosen = 23/45 = .511 So, the probability that a boy is chosen = 1 - .511 = .489
What is the probability a girl is chosen if 15 students are girls and 10 students are boys?
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.
What is the probability a boy is chosen if their are 26 kids and 10 are girls?
If 10 out of 26 are girls, then the probability of randomly choosing a boy is 16 out of 26, or 8 out of 13, or about 0.6154.
What if a class of 25 students has 15 girls and boys if one student is chosen at random what is the probability it is a girl?
The probability is 15/25 = 3/5
What is probability 2 girls are chosen if 10 students are girls and 15 are boys?
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%
What is the probability of a girl being chosen if there are 10 boys and 14 girls?
If the choice is unbiased, the change is 14/(10+14). If the chooser prefers choosing boys, the probability is 0.
A class of 25 students has 15 girls and 10 boys If one student is chosen at random What is the probability it is a girl?
The probability is 15/25 = 3/5
A family has 8 girls and 4 boys. A total of 2 children must be chosen to speak on the behalf of the family at a local benefit. What is the probability that 1 girl and 1 boy will be chosen?
