Mean for each hour = 1
Mean for four hours, m = 4
P(x,m)=m^x*e^(-m)/x!
where x is number of defects.
P(X<=3,4)
=P(X=0,4)+P(X=1,4)+P(X=2,4)+P(X=3,4)
=0.01832+0.07326+0.14653+0.19537
=0.43355
Probability of at most 3 defects in four hours is 0.43355
The probability of picking blue is stated as 2/10 which can be reduced to 1/5
multiply the number of times they pick a marble ( shown as 200) by the probability of picking a blue one ( 1/5)
200 x 1/5 = 200 / 5 = 40
Quinn can expect to pick blue 40 times
