If a football team has a 90% chance of making a field goal for three points and 35% chance of making a touchdown for seven point find the expected value of a touchdown

Step-by-step 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:

126 maybe. sorry

a) 0,0; 1,1; and 2,2

step-by-step explanation:

these have the exact same coordinates, thus they are the correct function.
