2. Six students randomly seated at a round table. What is the probability that three opredelѐnnye will close?

3. How long does it take the parts to the most probable number of suitable components were equal to 65, if the probability that the item will be taken at random defective is 0.05?

4. All the products are checked by two plant supervisors, the first supervisor checks 65% of the products, and the second - the other. The probability that the first controller will skip the non-standard product is 0.03, the second - 0.05. Taken at random product labeled as a standard, it was unusual. Find the probability that it is checked by a second controller.

5. Weekly production output at the plant is distributed approximately normal distribution with a mean of 14,678 units. production week and standard deviation 4670 units. Find the probability that the weekly output is lower than 8876 units. in a week.
