Mutually Exclusive Events, Independent Events, Complement Of An Event

 Lesson 1

Problem: One card is drawn from a standard deck of cards. Find the probability of drawing diamond card or a ten card.

Step 1: Probability of drawing a diamond card, P(A) = 13/52

Step 2: Probability of drawing a ten, P(B) = 4/52

Step 3: Probability of drawing a red card or ten =P(A)+P(B)–P(A and B)

= 13/52 + 4/52 – 1/52

= 16/52

Step 4:

The answer is:  4/13

Try two practice problems:

A.	One card is drawn from a standard deck of cards. Find the probability of drawing a spade card or an ace card.
B.	Drawing a four and drawing a three from a standard deck of cards. Are these events mutually exclusive?
