Michael is cutting a deck of cards for $1,000. What is the probability that the card is a face card?

There are 12 face cards in a deck. There are 52 cards in a deck (no jokers). The probability of finding a face card in one try is, therefore
Probability\, of\, a\, face\, card\, =\, \frac {12}{52}\, =\, \frac {3}{13}\, \approx\, 23.08%
Hope he doesn't bet the bank.

Could you please show me how to calculate this:
The quality control process at a manufacturing plant requires that each lot of finished units be sampled for defective items. Twenty units from each lot are inspected. If five or more defective units are found, the lot is rejected. If a lot is known to contain 10% defective items, what is the probability that the lot will be rejected and accepted?
