The cards numbered from 5 to 9 are 5 cards, specifically 5, 6, 7, 8, and 9. But there are four suits: diamonds, hearts, spades, and clubs. Therefore you multiply 5 by 4 to get 20. The probability of getting dealt one of those cards would be 20/52, or 5/13. But you want the probability of not getting such a card, so it's 1-5/13, or 8/13. That's the answer.

Two cards, the 4 and the 8, but there are four suits so it's 2 times 4 which is equal to 8. 8/52 = 2/1304/28/19

You randomly select one card from a 52-card deck. Find the probability of selecting a four or an eight04/28/19
