Answer 1

Given   : Joshua, Audrey, and Simone pick tiles marked A, B, and C from a bag, replacing each tile before the next pick. They repeat this process 120 times and record their results in this table.

Letter Times Picked

A 24

B 66

C 30

To Find :

The relative frequency of picking A is .

The relative frequency of picking B is .

The relative frequency of picking C is

Solution :

Letter Times Picked

A            24

B            66

C            30

Total      120

The relative frequency of picking A is .  =  Number of times A picked / total numbers  

= 24/120

= 1/5

The relative frequency of picking B is  =  Number of times B picked / total numbers  

= 66/120

= 11/20

The relative frequency of picking C is

=  Number of times C picked / total numbers  

= 30/120

= 1/4
