After a week of observation a supervisor determines that there is an 85% probability that 1 customer service representative will be on the phone with a customer at any given time.

You can put this solution on YOUR website! A software company has 3 customer service representatives. After a week of observation a supervisor determines that there is an 85% probability that 1 customer service representative will be on the phone with a customer at any given time. What is the probability of all 3 representatives being on the phone at the same time? Round to the nearest percent if necessary.
-------------------
Assuming the actions of the reps are independent you get:
---
P(3 on phone) = 0.85^3 = 0.6141 = 61.41%
