Question

Four balls are to be drawn without replacement from a box containing 8 red and 4 white balls. If X denotes the number of red ball drawn, find the probability distribution of X.

Answer 1

Total number of balls=8+4=12

Total number of possible outcomes=12

Number of red balls (X)=8

Therefore,number of favourable outcomes=8

Probability distribution of X=8/12=2/3

The answer of the probability distribution of X is 2/3.
