The probability distribution below describes the number of thunderstorms that a certain town may experience during the month of August.

Let X represent the number of thunderstorms in August.

X 0 1 2 3
P(X) 0.1 0.3 B 0.3

Determine the value of B
What is the expected value of thunderstorms for the town each August?
What is theVariance value of thunderstorms for the town each August?
Find the Mode of this probability distribution.
Find the CDF for X (cumulative density function).
Find the probability that at least 1 thunderstorm that the town may experience during August.
