The phone calls to a computer software help desk occur at the rate of 2.1 per minute between 3:00 p.m. and 4:00 p.m. Compute the
probability that the number of calls between 3:10 p.m. and 3:15 p.m. is
1 answer:
Answer:
The probability is 1/12
Step-by-step explanation:
Probability is given by number of possible outcomes ÷ number of total outcomes
Rate of phone calls = 2.1 per minute
Total number of calls between 3:00 p.m and 4:00 p.m (60 minutes) = 2.1 × 60 = 126
Number of calls between 3:10 p.m and 3:15 p.m (5 minutes) = 2.1 × 5 = 10.5
Probability = 10.5/126 = 1/12
