UGC-NET Computer Science July 2016 Solved Paper 2

Q::4 There are three cards in a box. Both sides of one card are black, both sides of one card are
red, and the third card has one black side and one red side. We pick a card at random and
observe only one side.
What is the probability that the opposite side is the same color as the one side we
observed ?
(1) 3/4                                  (2) 2/3
(3) 1/2                                  (4) 1/3

Answer:: (2)

Explanation::

Total number of cases = 3 i.e. (BB,RR,BR) Preferred number of cases =2 (BB,RR) since 2 cards have the same colour both sides. Probability = 2/3.
