The 9th hole at Segreganset Country Club is a par 4 hole measuring 440 yards. Over the course of a 4 hour span, 50 golfers played this hole. The following table represents X = the score a player received on the hole. Answer the following questions based on the table:
X Frequency
1 0
2 0
3 4
4 12
5 20
6 10
7 4
8 0
According to a study, 45% of Americans get their license before they are 18 years old. Suppose we randomly ask 20 individuals over the age of 18 if they got their license before they were 18 years old. Let X = the number of individuals who got their license before their 18th birthday.

To find the probabilties simply divide the individual frequencies by the sum of all the frequencies (which, in this case is 50).
X p(x)
1 0/50 = 0
2 0/50 = 0
3 4/50 = 0.08
4 12/50 = 0.24
5 20/50 = 0.4
6 10/50 = 0.2
7 4/50 = 0.08
8 0/50 = 0
To calculate the mean score multiply each score by its corresponding probability and add them all up.
i.e. mean = 1*0 + 2*0 + 3* 0.08 + ... + 7*0.08 + 8*0 =
This should help get you started.
