18 soil samples are collected to check for a particular pollutant. There is a probability of 0.25 that each sample contains the pollutant. Assume that these samples are independent. If X is the number of samples that contain the pollutant: a find the probability that the pollutant is present in exactly 6 samples b. find the probability that 35 X <8.
