Answer the following probability theory questions:
a) Roll a pair of dies (dice). What is the probability that the sum of the dots is 6? What is the probability of getting a 1-1, 2-2, or 3-3?
b) Assume that the probability of a PC being “dead on arrival” (DOA) due to an independent manufacturing defect is 1 in 100. If you order 300 PCs for (say) your business, what is the probability that the first PC you unpack and install is DOA?
