Answer:
a. 0.55
b. 0.68
c. 0.18
Step-by-step explanation:
a. The probability that E2 does not occur is one minus the probability that E2 occurs:
b. The probability that either E1 or E2 occurs is given by the sum of their individual probabilities minus their joint probability:
c. The probability that neither E1 nor E2 occurs is one minus the probability of E1 occurring minus the probability of E2 occurring:
Essentially, 50% of $10.56 is $5.28.
This means that all we have to do is add $10.56 to $5.28, making <u>$15.84</u>
Side note: Another way that you can do this is by simply doing 1.5(10.56).
