Question 1062196
a.  There are 52 cards in the deck, and the 6 of diamonds is just one of them.  So Pr{drawing 6 diamonds} = 1/52
—
b.  There are 13 clubs in a deck of cards, so Pr{drawing a club} is 13/52 = 1/4
—
c.  If you randomly chose a card, you have 1/52 chance of that being the exact card you want.  If you then draw a 2nd card there is a 1/51 chance of it being the 2nd card you hoped to see.  I assume no replacement.  Thus, Pr{draw 4 of clubs followed by draw 7 of hearts} = (1/52)(1/51) = 1/2652.
