Two bad eggs are accidently mixed up with ten good ones. Three eggs are drawn at random with replacement from this lot. compute the mean for the number of bad eggs drawn.

Two bad eggs are accidentally mixed with 10 good ones. 3 eggs are drawn at random with replacement from this lot. i. Compute mean for the number of bad eggs drawn. ii. Hence calculate variance and standard deviation .

Four bad eggs are accidentally mixed with 10 good ones. Three eggs are drawn simultaneously at random. Find the mean and variance of the bad eggs drawn.

Five defective mangoes are accidentally mixed with 15 good ones. Four mangoes are drawn at random from this lot. Find the probability distribution of the number of defective mangoes.

Four defective oranges are accidentally mixed with sixteen good ones . Two oranges are drawn at random from the mixed lot. If the random variable X denotes the number of defective oranges then find the values of X and number of points in its iverse image.

Four defective oranges are accidentally mixed with sixteen good ones. Two oranges are drawn at random from the mixed lot. If the random variable 'X' denotes the number of defective oranges, then find the values of 'X' and number of points in its inverse image.
