Having trouble working out the following problem for my son. Two cards are randomly selcted from a standard 52 card deck. What is the probability of getting two hearts or two cards less than four( aces count as 1)?
The probability of getting two hearts OR two cards less than four is P(Two Hearts) + P(Less Than Four) - P(Two Hearts AND Less Than Four).
See if you can suss out the problem now, and see if you get why why subtract that last probability from the combination of the two.
