Question 611114
You are on the right track.
But you said there are 5 chances out of 15 that the card is less than 5. IN fact, there are only 4 chances (1, 2, 3 and 4) . The fifth card would be a 5, which is NOT less than 5.
so {{{4/15 * 4/15 = 16/225}}}

For b, you have 4/15 at less than 5 and 3/15 at greater than 12
{{{4/15 * 3/15 = 12/225 = 4/75}}}

Do those match the answers??
