Question
The Mooncents Coffee Shop has an established discrete probability distribution for the morning demand for it's special "Wake Up Peoria" espresso drink. That probability distribution is as follows Wake Up" espressos served per moning Probability 0.04 0.12 0.18 0.24 0.13 0.15 0.10 0.04 2 4 5 7 a. What is the probability that there are less than 5 of these espressos served per morning? (Round your answer to 2 decimal places.) Probability b. What is the probability that there are 5 or more of these espresso drinks served per morning? (Round your answer to 2 decimal places.) Probability c. What is the probability that the number of "Wake Up Peoria" espresso drinks served per morning is strictly between 4 and 7? (Round your answer to 2 decimal places.) Note: by "strictly between" I mean minimum drinksExplanation / Answer
a) The probability that there are less than 5 of these expressos served per morning is 0.04 + 0.12 + 0.18 + 0.24 =0.58
b)
P(5 or more of these espresso drinks served per morning ) = 1- 0.58 = 0.42
c)
P( lies between 4 and 7) = P(X = 5 or X = 6)
= P(X= 5 ) + P(X= 6)
= 0.13 + 0.15 = 0.28
