2) Since she picked 100 balls and the probability that a ball is yellow is 0.10, multiply the probability times
the total number of balls. Number of yellow balls = 0.10 x 100 = ???
Place this answer into the table.
Since she picked a total of 100 balls and you now know the number of blue balls, red balls, and yellow
balls, subtract to find the number of green balls.
Place this answer into the table.
To find the relative frequency of the blue balls, divide the number of blue balls (32) by the total number
of balls (100) and place this decimal into the table.
To find the relative frequency of the red balls, divide the number of red balls (20) by the total number
of balls (100) and place this decimal into the table.
Do the same process to find the relative frequency of green balls.
If she picks another 250 balls, she should expect to get about 0.20 x 250 = ??? more red balls.
The total number of red balls expected would be the number you just calculated added to 20, the
number that she already had.
