Experimental Probability

Write a fraction to describe the probability of each event when pulling
a ball from the bag.

Pulling ball 1 11
Pulling ball 2 4 32
Pulling ball 3

Step 1. How many balls are in the bag?

Step 2. How many balls are there for each number, 1 , 2 , and 3 ?

Step 3. Write a fraction to describe the probability of pulling each ball,
1 , 2 , and 3 ?

Pulling 1 : Pulling 2 : Pulling 3 :
