To identify:The probability of increased sales. Sixty percent of a company's sales representatives have completed training seminars. Of these, 80% have had increased sales. Overall, 56% of the representatives (whether trained or not) have had increased sales. Use a tree diagram to given that a representative has not been trained.
The probability of increased sales, given that a representative has not been trained is 0.2 or 20%
Given information:
Sixty percent of a company's sales representatives have completed training seminars. Of these, 80% have had increased sales. Overall, 56% of the representatives (whether trained or not) have had increased sales.
Explanation:
Consider the given information.
Let 7 shows the event that the sales representative is trained and NT shows the event that the sales representative is not trained. Since 60% of the sales representatives have completed training seminars so
Following is the tree diagram:
Over 56% of the representative have had increased the sales so
Probability of increased sales given that a representative has not been trained
So, the probability of increased sales, given that a representative has not been trained is 0.2 or 20%
