  1. Answer:

    0.616

    Step-by-step explanation:

    The number of Us quarters is 43 while the number of Canadian quarters is 7.

    The number of quarters we are to pick is 6

    Mathematically, the probability of getting at least one Canadian quarter = 1 – probability of getting no Canadian quarter

    This means we have to calculate the probability of getting no Canadian quarter first.

    The total number of possible outcomes is 50C6 = 15,890,700

    If we are to get all to be US quarters, that means we are getting exactly 6 out of 43 = 43C6 = 6,096,454

    Hence, probability of no Canadian quarters is 6,096,454/15,890,700 = 0.384

    The probability of at least 1 Canadian quarters is thus 1-0.384 = 0.616
