A telemarketing company calls telephone numbers chosen at random. It finds that 70% of calls arc not completed (the party does not answer or refuses to talk), that 20% result in talking to a woman, and that 10% result in talking to a man. After that point, 30% of the women and 20% of the men actually buy something. What percentage of calls result in a sale? (Draw a tree diagram) What percent of sales are made to women?

We conclude that the 8 % of calls result in a sale.

We conclude that the 5.3% of sales are made to women.

Step-by-step explanation:

We know  that 70% of calls arc not completed (the party does not answer or refuses to talk), that 20% result in talking to a woman, and that 10% result in talking to a man.  After that point, 30% of the women and 20% of the men actually buy something.

We calculate what percentage of calls result in a sale, and we get:

We conclude that the 8 % of calls result in a sale.

We know that the ratio of women to men talking on the telephone is 2:1.

We calculate a percent of sales are made to women, and we get:

We conclude that the 5.3% of sales are made to women.
