Using the expected value, it is found that the mean of the distribution equals $0.1.
- The expected value, which is the mean of the distribution, is given by <u>each outcome multiplied by it's probability</u>.
The probabilities of <u>each outcome</u> are:
- .0000001 probability of earning $1,000,000.
- .9999999 probability of earning $0.
Thus, the mean is given by:
Thus showing that the expected value is $0.1.

Answer: Our required probability is 0.58.
Step-by-step explanation:
Since we have given that
Number of students worked in Nursing home = 11
Number of students worked in Tutoring center = 13
Number of students worked in Soup kitchen = 8
Number of students worked in Library = 18
Total number of students = 50
Since 3 students are selected from the club.
We need to find the probability that none of the three students volunteer at the soup kitchen.
So, Remaining students would be 50-8 = 42
So, probability that none of three students at the soup kitchen is given by
Hence, our required probability is 0.58.
