MT1203: Probability Theory and Mathematical Statistics
Option 4
Task 1. To perform the work, you need to select a group of four among ten people. How many ways can this be done?
Task 2. Produce two shots. Event A - hit the first shot, event B - hit the second shot. What is an AB event?
Task 3. There are four standard parts in a batch of six parts. Naudachu selected three parts. To compose the distribution law of a discrete random variable X - the number of standard parts among the selected.
Explanation: In task 3, in any of the variants you have chosen, write a solution and fill the distribution table with a random value. Sample table:
X 0 1 2 3 4
P ... ... ... ... ...
