Question

if you draw one card from the deck then roll fair dice and finally flip one fair coin what is the probability that you get an even numbered card or heads on the coin or both?

Answer 1

There are 5 even numbered cards in a 52 card deck.

Either/Or Probability for Overlapping Events The probability that either of two events occurs is equal to the sum of the probabilities of the two events, minus the joint probability of the two events happening together. Also known as the "General Addition Rule".
