Answer:
The probability that none of the 10 calls result in a reservation is 0.60%. In turn, the probability that at least one call results in a reservation being made is 99.40%.
Step-by-step explanation:
Since approximately 40% of the calls to an airline reservation phone line result in a reservation being made, supposing an operator handles 10 calls, to determine what is the probability that none of the 10 calls result in a reservation, and what is the probability that at least one call results in a reservation being made, the following calculations must be performed:
0.6 ^ 10 = X
0.006 = X
0.006 x 100 = 0.60%
Therefore, the probability that none of the 10 calls result in a reservation is 0.60%.
100 - 0.60 = 99.40
In turn, the probability that at least one call results in a reservation being made is 99.40%.

1) Average of six people = # of truffles / 6 = 7 ⇒ # of truffles = 6*7 = 42.
2) Average of first four people = # of truffles of the first four / 4 = 8 ⇒ # of truffles of the first four = 4*8 = 36
3) # of truffles of the fourth person = 11
4) # of truffles of the first three people = 36 - 11 = 25
5) # of truffles of the last three people = 42 - 25 = 17
Answer 17.
