1.If you are dealt 3 cards from a shuffled deck of 52 cards, find the probability that all 3 cards are queens.
Sol: There are 4 queens in a deck of 52 cards.
Probability that a card pulled out is a queen: p = 4/52 = 1/13.
Number of trials = 3
Therefore, the probability that each of the three cards is a queen = p*p*p
= 0.000455

Sol: Probability that a head is got = p = 0.5
Probability that a tail is ...
