If in a frequency distribution, the mean and median are 21 and 22 respectively, then its mode is approximately
Solution : Given that, mean = 21 and median = 22 Using the relation, Mode = 3 median – 2 mean \(\implies\) Mode = 3(22) – 2(21) = 66 – 42 = 24 Similar Questions The mean and variance of a random variable X having a binomial distribution are 4 and 2 respectively, then P(X […]
