Total number of unit tests taken = 5 We know, Probability of an event = (Number of Favorable outcomes) / (Total Numbers of outcomes) (i) Number of times student got more than 70% = 3 Probability (Getting more than 70%) = 3 5 = 0.6 (ii) Number of times student got less than 70% = 2 Probability (Getting less than 70%) = 2 5 = 0.4 (iii) Number of times student got a distinction = 1 [Marks more than 75%] Probability (Getting a distinction) = 1 5 = 0.2
