Answer:

0.23328,2.4

Step-by-step explanation:

Given that an airport limousine can accommodate up to four passengers on any one trip. The company will accept a maximum of six reservations for a trip, and a passenger must have a reservation.

Assuming independence we can say persons who do not show up is binomial with p = 0.4 and n = 6

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

= P(X\leq 1)\\=0.23328

b) Expected no of available places = E(x)=np = 6(0.4) = 2.4

By the law of cosines, the angle C satisfies

8.77^2=2^2+9^2-2\times2\times9\times\cos C

which reduces to

\cos C=0.2246\implies C=\arccos(0.2246)\approx1.34422\text{ rad}

which converts to approximately 77 degrees (this can be done my multiplying by 180 and dividing by pi).
