Suppose the probability distribution of X = the number of jobs per student at a university in the past year is as follows:_____________.
—————— —— —— —— —— —— Number of jobs X 0 1 2 3 4 Odds 0.14 0.37 0.29 0.15 0.05 —————— —— —— —— —— ——
Then, choosing a random student, what is the probability that they had one or two jobs during the past year, such as P (X = 1 or X = 2)?
