Answer:
In 300 draws Ellen should expect to draw a blue marble 120 times.
Step-by-step explanation:
Number of red marbles = 3
Number of blue marbles = 2
Total number of marbles = [tex]3+2=5[/tex]
Probability of drawing blue marbles = [tex]\frac{numberof possible outcomes}{total number of outcomes}[/tex]
=> [tex]\frac{2}{5}[/tex] = 0.4
Total number of draws = 300
So, in 300 draws Ellen should expect to draw a blue marble:
[tex]0.4\times300=120[/tex] times.
And in case if red is needed, it becomes: [tex]0.6\times300=180[/tex] times.
