Question

One ballispicked at random from a box containing 3redballs and 1green balls. If X is the number of redballs picked, find the probability distribution of X.

Answer 1

P(X = 0) = 0.25

P(X = 1) = 0.75

Explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

The probability distribution of X.

3 red balls out of 4, one picked, so we can have either 0 red balls or 1 red ball. The probability disitribution is the probability of each outcome.

`P(X = 0) = (1)/(4) = 0.25`

`P(X = 1) = (3)/(4) = 0.75`
