Answer:
$2000
Step-by-step explanation:
For each pound, the charge is $40. There are 50 such charges. The point of multiplication is to simplify the process of repeated addition.
... 50 × $40 = $2000
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
