Answer:

Explanation:
We look for the expected value for a touchdown.
If X represents the number of points scored per touchdown scored, then X is a discrete random variable, and by definition, the expected value V (X) for a discrete random variable is defined as:

Where P(X) is the probability that X will occur.
In the sample space of the random variable X there are two possible values.
points (1 touchdown) with
points (0 touchdown) with

Then the expected value V(X) is:
