The time to failure for a TV is modeled by this equation f(t) = 0.02e -0.02t. Should I start this problem off by looking at the T table getting the value and multiple it by the 0.02..

I'm going to say no that isn't what you should do.

It's impressive that I can say that too since you never actually said what the problem is...

A Manufacturer offers a 3 year warranty on a TV. if the tv fails during this rime they must repalce the unit. The time tofailure for their TV's is well modeld by the equation f(t) = 0.02e -0.02t. What percentage of TV's will need to be replaced due to warranty claims. I thought maybe because of the F(t) that I would need to get the T value to start. Thanks

You just need to find the CDF of the failure times and plug in t = 3 into the cdf.
