Two different dice are thrown together, find the probability that the sum of the numbers appeared is less than 5.

Answer»

Total number of outcomes = 6 × 6 = 36 

Favourable outcomes = {(1, 1)(1, 2)(1, 3)(2, 1)(2, 2)(3, 1)} 

Number of favourable outcomes = 6

P(less than 5) = \(\frac{6}{36}\) = \(\frac{1}{6}\)
