Let the mean and variance of 7 observations 2, 4, 10, x, 12, 14, y, x > y, be 8 and 16 respectively. Two numbers are chosen from 1, 2, 3, x-4, y, 5 one after another without replacement, then the probability that the smaller number among the two chosen numbers is less than 4, is: | Watch the step-by-step video solution for this NIMCET PYQ.
