The 2019 Farmer’s Insurance Open is a golf tournament that took place between January 24th and January 27th of 2019. The 18th hole is considered to be one of the hardest of the tournament. Let X be the number of golf strokes taken to complete the 18th hole. The probability distribution for X is:
X: 2 . 3 . 4 . 5
P(X): 0.064 . 0.673 . ??? 0.019
Find the expected number of strokes needed to complete the hole.
A) 3.218
B) 2.242
C) 0.244
D) 0.756
Solution:-
x | P(x) |
2 | 0.064 |
3 | 0.673 |
4 | ? |
5 | 0.019 |
Expected number = 0.064+0.673+0.019 -1
= 0.756 - 1 = 0.244
= 0.244
Answer = C) 0.244 OPTION IS CORRECT
