What values does X take on?

Short Answer

Expert verified

Because X denotes the number of community events at which Sam has volunteered in a given month, the random variable's values are0,1,2,3,4,and5. This is due to Sam's practice of not volunteering for more than five events per year.

Step by step solution

Given Information

At community events, volunteers. He only attends five events per month. He attends exactly five activities 35% of the time, four events25%of the time, three events 20% of the time, two events 10%of the time, one event 5% of the time, and no events 5% of the time.

On May 11, 2013 at 9:30 PM, the probability that moderate seismic activity (one moderate earthquake) would occur in the next 48hours in Japan was about 1.08%. As in Example 4.8, you bet that a moderate earthquake will occur in Japan during this period. If you win the bet, you win \(100. If you lose the bet, you pay\)10. Let X = the amount of profit from a bet. Find the mean and standard deviation of X.
