The following table gives the number of usable years that a customer will get out of a television set.
What is the probability that a customer gets more than 2 years of usable life out of a television set?
| Number of usable years | 1-2 | 3-4 | 5-6 | 7-8 | More than 8 |
|---|---|---|---|---|---|
| Probability | .05 | .32 | .41 | .13 | .09 |
Solution
P(more than 2) = 1 - P(1 - 2 years)
= 1 - 0.05
= 0.95 (ans)
