If 15 have high blood pressure and 25 have high level of cholesterol, a how many people have high blood pressure and a high level of cholesterol? A committee of 5 people is to be formed randomly from a group of 10 women and 6 men. Find the probability that the committee has a 3 women and 2 men.

A group of 8 students is chosen at random. Find the probability that a exactly 5 have access to the internet. The grades of a group of students in an exam are normally distributed with a mean of 70 and a standard deviation of A student from this group is selected randomly. In a certain country last year a total of million tons of trash was recycled.

The chart below shows the distribution, in millions of tons, for the different types of trashes.The binomial distribution is a discrete probability distribution. It describes the outcome of n independent trials in an experiment.

Each trial is assumed to have only two outcomes, either success or failure. If the probability of a successful trial is p, then the probability of having x successful outcomes in an experiment of n independent trials is as follows.
