A day’s production of 850 parts contains 50 defective parts. Three parts are selected at random without replacement. Let the random variable ? equal the number of defective parts in the sample.
1. Find the probability mass function
2. Find the cumulative distribution function of ?.
3. Find ?(? > 0.5) =
4. Find ?(1.5) =
5. Find ?(2) − ?(0.3) =
6. Find ?(0.99 < ? < 2.5) =
