Question 1172328: An urn contans 8 balls from number 1 to 8. Four ball are drawn random and without replacement. Let A be the event that exactly two even numbere balls are drawn and they occur on even numbered drawns from the urn. What is probability of event A.

The first draw has to be an odd number (4/8) probability. The second has to be an even number and that is (4/7) probability. The third has to be odd with (3/6) and the fourth has to be even with (3/5) probability.
This joint probability is (1/4)(12/35)=3/35
