Question

The probability of a volunteer receiving the caffeinated drink and getting more

energy was 35%. What is the probability of a volunteer getting more energy, given that the
volunteer received the caffeinated drink?

Answer 1

Answer: 0.7 or 70%

Explanation:

A = volunteer receiving caffeinated drink

B = volunteer getting more energy

P(B|A) = P(A and B) / P(A)

P(A and B) = 0.35

Without more information, we cannot determine P(A) exactly, but let's assume that it is 50%

Then, P(A) = 0.5, and P(B|A) = 0.35 / 0.5 = 0.7

So the probability of a volunteer getting more energy, given that they received the caffeinated drink, is 0.7 or 70%.
