A card is drawn from an ordinary deck. Find these probabilities. 1 Of getting a jack 2 Of getting the 6 of clubs (i.e., a 6 and a club) 3 Of getting a 3 or a diamond 4 Of getting a 3 or a 6

Answer 1

There are 52 cards on a deck

probability = number of desired outcomes/total possible number of outcomes.

total possible number of outcomes is always 52

1) getting a jack - there are 4 jacks in a deck, so the number of desired outcomes is 4

2) getting 6 of clubs - there is one such card - so the number of desired outcomes is 1

3) getting a 3 or a diamond - there are 4 3's and 13 diamonds, however there is a 3 of diamonds, so there are 4 + 13 = 1 = 16 desired outcomes.

4) there are 4 3's and 4 6's, so there are 4 + 4 = 8 desired outcomes
