Answer:
(a)Yellow=10
Green=38
Relative Frequency of Blue =0.32
Relative Frequency of Red =0.2
Relative Frequency of Green =0.38
(b)50 Red balls
Step-by-step explanation:
In 100 trials, the following were recorded.
Frequency of Blue Balls = 32
Frequency of Red Balls = 20
Relative Frequency of Yellow Balls =0.1
Now, Relative Frequency =Number of Outcome of an Event ÷ Total Number of Trials in the Experiment
Total Number of Trials =100
Therefore:
Therefore, Number of Outcomes of Green balls=100-(32+20+10)
=100-62
Number of Outcomes of Green balls=38
(b)If the Number of Trials is Increased to 250
Expected Outcome of Red Balls =Relative Frequency of Red Balls X 250
She should expect 50 red balls.
