<u>Here is given two events in which one is occuring(rasberry flavour) and other(cola flavour) is not occuring, we have to find the probability of not occuring events(cola flavour)</u>.
We know that,
P(E) + P(Ē) = 1.
P(R) + P(C) = 1.
0.29 + P(C) = 1
P(C) = 1 - 0.29
P(C) = 0.71
<u>It means probability of cola flavour cup drink is 0.71</u>
