A standard deck of 525252 cards contains 444 suits: hearts, clubs, diamonds, and spades. Each suit consists of cards numbered 222 through 101010, a jack, a queen, a king, and an ace. Zhi Qing decides to pick one card at random from a standard deck of 525252 cards. Let AAA be the event that she chooses a three card and BBB be the event that she chooses a seven card. What is P(A\text{ or }B)P(A or B)P, (, A, start text, space, o, r, space, end text, B, ), the probability that the card Zhi Qing chooses is either a three or a seven?

2/13

Step-by-step explanation:

Number of Cards in a Deck, n(S)=52

A is the Event that she picked a three card.

n(A)=4

B is the Event that she picked a seven card.

n(B)=4

P(A)=n(A)/n(S)=4/52

P(B)=n(B)/n(S)=4/52

P(A or B)=P(A)+P(B)

=4/52+4/52

=8/52

=2/13

The probability that the card Zhi Qing chooses is either a three or a seven is 2/13.
