Question

The phone lines to an airline reservation system are occupied 40% of the time. Assume that the events that the lines are occupied on successive calls are independent. For the next 10 calls to the airlines, what is the probability that exactly 3 of the calls will get an occupied line? Round your answer to 3 decimal places. For the next 10 calls to the airlines, what is the probability that at least 1 call gets an occupied line? Round your answer to 3 decimal places.

Step 1

Given that the probability of an occupied line is 0.4 and the probability of not being occupied is 0.6, we can use the binomial probability formula: \[ P(X = 3) = \binom{10}{3} \times (0.4)^3 \times (0.6)^7 \] \[ P(X = 3) = \frac{10!}{3!(10-3)!} \times 0.064 Show more…
