A solar panel manufacturer does some testing and finds out (to their horror) that on average 22% of their solar panels have some type of defect. Assume that defects are independent. 3 (a) What distribution describes the probability of the number of tests until a defect is found? Define all parameters and give their values. (b) What is the probability that the first defect is found on the 10th trial? C 3 (c) What is the minimum and maximum value for this distribution? (d) What is the probability that a defect is found on or before the 2nd test. Show your workings
