Question 1148497
<br>
The "1 in 10" and "1 in 50" are probabilities, not odds.<br>
a. P(pizza or large drink) = 1/50+1/10 = 6/50 = 3/25<br>
b. P(neither) = 1 - P(pizza or large drink) = 1-3/25 = 22/25<br>
c. P(neither 3 times in a row) = (22/25)^3 = 10648/15626<br>
d. P(at least one in next 3 visits) = 1 - P(neither in any of next 3 visits) = 1-10648/15626 = 4977/15625<br>
