Question 35136
OK you pick 4 numbers from 40 choices. What is the probability of those appearing?


First number picked being one of yours = 4/40
Second number picked being one of yours = 3/39
Third number picked being one of yours = 2/38
Fourth number picked being your last one = 1/37


So, {{{ P(winning the lottery) = (4/40)*(3/39)*(2/38)*(1/37) }}}
{{{ P(winning the lottery) = (1/10)*(1/13)*(1/19)*(1/37) }}}
is whatever..you work it out.
