probabality

Question

approximately 27% of calls to airline result in reservation. Suppose 10 operators handle 10 calls. What is probability that none of 10 calls result in reservation?

Answer 1

P(no reservation, 1 call) = 0.73

 

P(no reservations, 10 calls) = 0.73¹⁰ = 0.043, to 3 Decimal Places.  Not very likely!
