second polynomial. In this case, we need to distribute the 4x and the
–5.

Answer:
If the probability of a good year is 0.3 and the probability of a bad year is 0.7, we can multiply these values by the number of storms that each one represents. So (0.3*5)+(0.7*6)= 5.7, this is the number of storms expected for the next year. For the variance, we need to do a summary between the average and the data collected, so {[(5-5.7)^2]+[6-5.7]^2}/2 = variance = 0.29, this means that the expected number of storms fro the nex year will be 5.7 +- 0.29.
Finally, the average number of expected storms for the next year is 5.7, with a variance of 0.29
