Answer:
Hi, this question is a little unclear. If you want to know what percentage he saved, it would be 30%, and to convert that percentage into a decimal would be a decimal of 0.30
Answer:
A: Diane earns 200 + (10×20)= 400
B: Darryl earns (400-250)/20= $7.50 per hour
Let BS be the event that the patient survives bypass surgery.
Let H be the event that the heart damage will heal.
Then P(BS) = 0.60, and also we have a conditional probability: GIVEN that the patient survives,
the probability that the heart damage will heal is 0.5, that is P(H|BS) = 0.5
We want to know P(BS and H).
Using the formula of the conditional probability:
P(H and BS) = P(H|BS)·P(BS) = (0.6)(0.5) = 0.3
