Question

A computer company wants to start a call center. They designed a simulation using a random number generator to predict the frequency of the types of calls they would receive. Solve for the situation.

Based on the simulation data, calculate the probability of the first call being a sales call.

28.6%

31.1%

32.8%

36.1%

Answer 1

The correct answer is B. 31.1%. This is the probability of the first call being a sales call.

Explanation:

1. Let's review the information given to us for solving the question:

There are six types of sales calls with a frequency of 19 calls for the simulation.

There are six types of informational calls with a frequency of 22 calls for the simulation.

There are nine types of technical support call with a frequency of 20 calls for the simulation.

Total of calls for the simulation = 19 + 22 + 20 = 61

2. Let's find the probability of the first call being a sales call.

Probability = Frequency/ Total of calls for the simulation

Probability = 19 / 61

Probability = 31.14% = 31.1% (Rounding to one decimal place)

The correct answer is B. 31.1%.

Probability of the first call being an informational call.

Probability = Frequency/ Total of calls for the simulation

Probability = 22 / 61

Probability = 36.06% = 36.1% (Rounding to one decimal place)

Probability of the first call being a technical support call.

Probability = Frequency/ Total of calls for the simulation

Probability = 20 / 61

Probability = 32.78% = 32.8% (Rounding to one decimal place)
