An investigator is interested in examining if drinking wells are contaminated with a toxin, the toxin is found in 29% of the wells within the region. 7 drinking wells were examined, they have selected the 7 wells so they are far enough apart from one another so the results of one drinking well provides no information as to the status of any other well in the study. a) What is the probability that exactly 3 of the wells in the study are contaminated. b) What is the mean and standard deviation of the number of drinking wells in a sample of this size that are contaminated.
