Unformatted text preview: p =0.6 and the outcomes of different games are independent. a) Evaluate the probability of winning 2 games out of 5. b) If you play until you win twice and then stop, what is the probability that you play exactly 3 times? 3. The Caspian Sea is a large lake with no outlet. Hence its water level fluctuates widely as a result of anomalous yearly water inflow, precipitation and evaporation. During wet years, the Caspian Sea level (CSL) increases by 0.3m and in dry years it decreases by 0.2m. Given that different years are independently wet or dry with probability P wet =0.4 and P dry =0.6, find the probability mass function of the change in CSL over a period of 4 years. 4. Read Application Examples 3, 4, and 5. (No problem assignment, but you may try on your own.)...
