PART B: Based on the probability in PART A, how many of the next 5,000 televisions manufactured should the company expect to be defective?

Answer 1

don't know how to start it off

Answer 2

The prob of a defective TV is the number of defective divided by the number of TV's tested

Answer 3

\[a) \space Prob \space (defective) \space = \frac{ 20 }{ 1000 } \space = \frac{ 2 }{ 100 } \space = \frac{ 1 }{ 50 } \space = .02 \]

Answer 4

\[b) \space Expected \space number \space defective \space = .02(5000) \space = 100\]
