Question

Asked Apr 9, 2019

The marketing department of a TV manufacturer has done research on the number of TVs owned by families in a large town. The probability model for the number of tvs owned by a randomly chosen family is given below. In the long run, what is the expected number of TVs per family? Round your answer to the nearest tenth.

Number of TVs | 0 | 1 | 2 | 3 | 4 |

Probability | 0.06 | 0.24 | 0.43 | 0.19 | 0.08 |

Step 1

**Expected value:**

The expected value of a discrete random variable *X* is defined as the sum of the product of the values of the random variable and the corresponding probability. That is,

Step 2

Let the random variable *X *denotes the number of TV owned by families in a large town. Here, the probability model for the number of T...
