Question

A card is drawn randomly from a deck of ordinary playing cards. You win Php 1000 if the cards is a spade or an ace. What is the probability that you win the game?​

Answer 1

Answer:

Winning cards are spades and there 13 of those in the deck - the numbers 2 through 10 (9 if them), the three face cards (J, Q, K), and the A. So there are 13 + 4 - 1 = 16 winning cards out of the deck of 52. Thus our probability is 16/52.0
