Question 907106
A radio station plays a game with a call-in contestant 4 times a day. The distribution below shows the probability distribution for the number of contestants that will win in a day.
Radio Game Show
Number of Winners	Probability
0	0.720
1	0.176
2	0.058
3	0.002
4	0.044 

(b) What is the probability that there is at least one winner on a randomly selected day? 

P(X ≥ 1) = 1 - P(X = 0) = 1 - 0.720 = {{{highlight(0.280)}}}

(c) What is the probability a that there are more than 2 winners on a randomly selected day? 

P(X > 2) = P(X = 3) + P(X = 4) = 0.002 + 0.044 = {{{highlight(0.046)}}}
