  1. probability of what? one one and the ten or two ones or what?
    I guess I will assume you mean what is the probability of getting ten plus one
    first draw, probability of ten = 1/5

    if you missed, you now have three ones and a ten
    probability of ten = 1/4

    so the total probability of getting the ten either on the first or on the second draw is
    1/5 + 1/4 = 9/20
