Answer:
The theoretical probability of receiving a technical support call is 12/54 or 22.2% (Rounding to one decimal place)
Step-by-step explanation:
1. Let's review the information given to us for solving the question:
There are five types of sales calls with a frequency of 18 calls for the simulation.
There are seven types of informational calls with a frequency of 24 calls for the simulation.
There are four types of technical support call with a frequency of 12 calls for the simulation.
Total of calls for the simulation = 18 + 24 + 12 = 54
2. Let's find the theoretical probability of receiving a technical support call.
Probability = Frequency/ Total of calls for the simulation
Probability of the receiving a technical support call.
Probability = 12/ 54
Probability = 22.22% = 22.2% (Rounding to one decimal place)
Answer: 25 %
Step-by-step explanation:
First we will add the values of the frequencies which is : 18 + 24 + 12 =54
were asked to find for the technical support so we will divide : 54 / 12 and we get 25%
So the Answer is 25%
