Trouble 66E

Problem 66E

An airdrome limousine can accommodate upwards to iv passengers on any one trip. The company will accept a maximum of six reservations for a trip, and a passenger must accept a reservation. From previous records, 20% of all those making reservations do not appear for the trip. Respond the following questions, assuming independence wherever advisable.

a. If six reservations are made, what is the probability that at least one individual with a reservation cannot be accommodated on the trip?

b. If six reservations are made, what is the expected number of available places when the limousine departs?

c. Suppose the probability distribution of the number of reservations made is given in the accompanying tabular array.

Allow X denote the number of passengers on a randomly selected trip. Obtain the probability mass function of X.

Given, An aerodrome limousine tin can accommodate up to four passengers on any one trip. The company will accept a maximum of half-dozen reservations for a trip, and a passenger must have a reservation. From previous records, 20% of all those making reservations practice not appear for the trip

If six reservations are made, the claim is to observe the probability that at to the lowest degree i individual with a reservation cannot be accommodated on the trip

Where, p = 0.80 and n = 6

P(at least one individual with a reservation cannot be accommodated on the trip) = P(x $\geq{}$ v)
