It is believed that 25% of the population is in favour of free railway transport, in order to reduce car emissions. If we take a random sample of n=30 what is the probability that either 4 or 5 are in favour? What is the probability that we ask 5 people, until we find the 1st that is in favour?

2. In a study of 437 comma 485 cell phone​ users, it was found that 54 developed cancer of the brain or nervous system. Assuming that cell phones have no​ effect, there is a 0.000168 probability of a person developing cancer of the brain or nervous system. We therefore expect about 74 cases of such cancer in a group of 437 comma 485 people. Estimate the probability of 54 or fewer cases of such cancer in a group of 437...

To determine whether or not they have a certain desease, 80 people are to have their blood tested. However, rather than testing each individual separately, it has been decided first to group the people in groups of 16. The blood samples of the 16 people in each group will be pooled and analyzed together. If the test is negative, one test will suffice for the 16 people (we are assuming that the pooled test will be positive if and only...
