6. In order to win the lottery, a player must correctly pick five unique 2-digit numbers randomly selected by a machine, in the right position.
a. What is the probability of winning this lottery?
b. Imagine a smaller prize is awarded if a player correctly picks exactly 4 of the five numbers (again, in the right position). What is the probability of winning either the smaller prize or the regular prize (i.e. what is the probability of winning anything)?
