An investor purchased 100 shares of 5/3 Bank stock and 100 shares of Santee Cooper Electric Shock. The probability the bank stock will appreciate over a year is .70. The probability the electric utility will increase over the same period is .60.
a. What is the probability both stocks appreciate during the period
b. What is the probability the bank stock appreciates but the utility does not
So I am guessing that for:
a. (100*0.7) + (100 * 0.6) is this right??
