1. Probability which exactly 27 items will be good.

2. Probability that five or less items will be defective

3. Probability that between 22 and 28 inclusive items inclusive will be good.(Inclusive means that the both 22 and 28 are included)

4. Probability that 25 or more items will be good.

5. Probability that 26 or more items will be good.

6. Probability that between 5 and 8 items inclusive will be defective.
