Four bad oranges are mixed accidently with 16 good oranges.Find the probability distribution of the number of bad oranges in a draw of two oranges.

Four bad oranges are mixed accidently with 16 good oranges find the probaility distribution of the number of bad oranges in a draw of two oranges

Four bad oranges are mixed accidently with 16 good oranges in box. Find probability distribution of bad oranges in a draw of two oranges.

Four bad apples are mixed accidentally with 20 good apples. If 3 apples are drawn one by one with replacement then mean of number of good apples is

If total number of apples is 250, the mean mass of the apples is

Five bad oranges are accidently mixed with 20 good ones.If four oranges are drawn one by one successively with replacement,then find the probability distribution of number of bad oranges drawn.Hence find the mean and variance of the distribution.

Five bad oranges are accidently mixed with 20 good ones. If four oranges are drawn one by one successively with replacement, then find the probability distribution of number of bad oranges drawn. Hence find the mean and variance of the distribution.
