Detailed explanation-1: -There are 52 cards in total. 13 of these are clubs and 4 are 4 but one is already counted as it is 4 of clubs so the total is 16 cards out of 52 so 16/52 roughly one third so roughly one of three cards is either a club or a 4.
Detailed explanation-2: -A card is drawn from a pack of 52 cards. The probability of getting an ace is 1/52.
Detailed explanation-3: -Therefore, we have a 28/52, or 53.85% probability of getting a 4, a club, or a spade.
Detailed explanation-4: -First, there are 52 cards in the deck, so the total number of outcomes is 52. But there are only 13 spades and 13 clubs, so that is the sample space. The probability of getting a spade, P(Spade), is 13/52 or 0.2500. Same for the probability of getting a club, P(Club) = 13/52 or 0.2500.
