To find: the probability

Answer to Problem 4.19E
The probability
Explanation of Solution
Given information:
As mentioned in problem two cards are drawn out of deck of cards.
Formula:
Total number of black cards is
Total probability
Calculation:
Consider the statement that two cards are drawn out of deck of cards.
Since total number of cards in the deck is
Two cards are drawn from the deck of cards.
Therefore
Recall that there are
Event of both black card are
Event of ace card are
Event of both black and ace card is
Recall
Recall
Recall that probability of both black and ace card
Therefore the probability
Therefore
Therefore probability
