Chapter 13.3, Problem 67AYU

Surveys In a survey about the number of TV sets in a house, the following probability table was constructed:

$\begin{array}{cccccc}\text{Number}\text{of}\text{TV}\text{sets}& 0& 1& 2& 3& 4\text{or}\text{more}\\ \text{Probability}& 0.05& 0.24& 0.33& 0.21& 0.17\end{array}$

Find the probability of a house having:

1. $1$ or $2$ TV sets

2. $1$ or more TV sets

3. $3$ or fewer TV sets

4. $3$ or more TV sets

5. Fewer than $2$ TV sets

6. Fewer than $1$ TV sets

7. $1,2$ or $3$ TV sets

8. $2$ or more TV sets
