Suppose 75% of chemotherapy patients suffer nausea. We randomly select two such patients (assume these two patients are independent).
----
i) Find the probability that both suffer nausea:::(3/4)^2 = 9/16
-----
ii) Find the probability that at least one suffers nausea:::
Ans = 1- (1/4)^2
= 1-1/16
= 15/16
