Question

A card is drawn from a standard deck of cards. Find the probability, given that the card is a non-face card.

P(eight)

The probability that the card is an eight given that the card is a non-face card is ______.
(round to two decimal places as needed)

Answer 1

0.10

Explanation:

The probability the card is an 8 given it is not a face card is the ratio of 8s in the deck to the non-face cards in the deck.

There are 4 eights in the deck, and 40 non-face cards:

p(8 | nfc) = 4/40 = 0.10
