A salesperson figures that the probability of her making a sale during th first contact with a client is 0.4 but improves to 0.6 on the second contact if the client did not buy during the first contact. Suppose this salesperson makes one and only one callback to any client. I she contacts a client, calculate the probabilities for the following event.

The client will buy?

The probability that the client will buy with making a call and then one more callback to the client is 0.6.

Explanation:

Probability is a numerical description of how likely an event is to occur or how likely it is that a proposition is true. Probability is a number between 0 and 1, where, roughly speaking, 0 indicates impossibility and 1 indicates certainty.

In the question above, there have two probabilities shown. One talks about the probability of buying a product by the client with making only one call made is 0.4. The other probability talks about client buying the product with two calls made to the client one call and one callback is 0.6. Since it is the second situation is happening in the question so the probability of the client buying the product is 0.6.

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50
