Question

(URGENT) The probability distribution for a game is shown in the table below.

What is the probability of not winning a cash prize if the game is played one time?


A 3/10

B 1/5

C 4/5

D 7/10

Answer 1

Answer: A) 3/10

This is the probability of winning 0 dollars, aka not winning any cash prizes. So all we do is write down the probability value found in the first column.

side note: you could add all the other probabilities to get 1/5+1/10+2/5 = 2/10+1/10+4/10 = 7/10, then subtract that from 1 to get 1-7/10 = 10/10-7/10 = 3/10. Though this is a bit more work than needed in this problem.
