Answer:
Probability that a gym member does not take weight-loss medication = 0.63
Step-by-step explanation:
Let E be the event of choosing a gym member who drank protein shakes and W be the event of choosing a gym member who took weight loss medication.
Probability that a gym member drank protein shakes = P(E) = 0.9
Probability that a gym member does not drink protein shakes = P(not E) = 0.1
E and W are independent events.
By using Bayes Theorem, P(E and W) = P(E)*P(W)
Probability that a gym member drank protein shakes and took weight loss medication = P(E and W) = 0.3*0.9 = 0.27
Probability that a gym member took weight-loss medication = P(W) = 0.1 + 0.27 = 0.37
(10% of members who did not drink protein shakes took weight-loss medication)
Therefore, Probability that a gym member does not take weight loss medication = P(not W) = 1 - 0.37 = 0.63
It would be the last option, (5, -4)
S1=$70/20gal=$3.50 per gallon
s2=$33.50/(50/4)gal=$2.68 per gallon
s3=$48.75/(15+8)gal=$2.12 per gallon
So supplier #3 has the best deal.
