Question

. A basket contains 5 red balls and 11 white balls. If two balls are taken from the

basket one after the other, determine the possible values of the random variable R

representing the number of red balls.

Answer 1

R shows how many of two taken balls are red. So the possible values of R are: 0 (only white balls), 1 (one red, one white), 2 (all red).

Answer: R= {0, 1, 2}.
