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?
