Explain why a selection of 10 students from your class can have marks that aren't normally distributed when the marks of the whole class are normally distributed?
The sample size is likely to be too small.
What is the probability that at least 2 people in the class of 25 will share the same birthday?
Birthdays are not distributed uniformly over a year but if, for the sake of probability games you assume that they are, then ignoring leap years, the probability is 0.5687. Including leap years, it is slightly lower.
A nursing class has 13 women and 18 men If a student is chosen randomly to be the team leader what is the probability the student is a woman?
The probability that a randomly chosen student is a woman can be calculated by dividing the number of women by the total number of students in the class. In this case, there are 13 women and 31 total students, so the probability is 13/31, which simplifies to approximately 0.419 or 41.9%.

How many school lets students bring food in class?
Not very many schools allow students to eat in class. This would be a total disaster and a mess if teachers allowed students to eat during class or eat in class during their lunch time. But somewhere in the world there are schools where teachers let you eat in your classrooms. you just have to look for a school that does. Even Penta doesn't let you eat in the classrooms.

If two students are chosen randomly at the same class what is probability to have the same birthday is it likely or unlikely?
It depends on how big the class is.
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
There are 10 boys and 12 girls in a class if one student is selected at random from the class what is the probability it is a girl?
The probability is the number of girls divided by the number of students, so 12/22, or 6/11
The probability that a given student will show up for the test is 0.9 if there are 27 students in the class what is the probability that everyone will show up?
.9^27, or approximately .058 = 5.8%
What is the probability that at least 2 people in the class of 25 will share the same birthday?
Birthdays are not distributed uniformly over a year but if, for the sake of probability games you assume that they are, then ignoring leap years, the probability is 0.5687. Including leap years, it is slightly lower.
Two students are chosen at random from a class of 30 what is the probability that both you and your best friend are chosen?
The probability of this is based heavily on whether or not said best friend is even in the class. If both are in, it's a 1/870 chance.Ê
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

about 25
Does classrooms of cameras?
no there is no cameras in the class room
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
