1. A card is drawn at random form a well shufled pack of 52 playing cards. Find the probability of getting neither ared card nor a green. |

Answer» Total number of Outcome (Cards) = 52 First eliminate half the deck, so as to get rid of the red cards. This leaves, 1/2× 52 = 26 Cards However, two queens were already gotten rid of when all the red cards were removed, leaving only two black queens.Thus, we take two black queens away from our remaining cards, 26 - 2 = 24 ∴ Number of Favourable Outcomes = 24 P(getting neither a Red nor a Queen) = 24/52 = 6/13 |
