Question

Three urns contain respectively 3 green and 2 white, 5 green and 6 white, and 2 green and 4 white balls. One ball is drawn from each urn. What is the probability distribution of the random variable "number of white balls drawn"?

Answer 1

Please check ur question as green and white are repeated twice

Answer 2

Answer:

Let W be the number of white balls drawn. As there are three urns, it is possible to draw zero white balls, up to three white balls. In other words, W=0 , W=1 , W=2 , and W=3 .

The following probabilities have been calculated (with no working shown):

P(W=0)=111

P(W=1)=58165

P(W=2)=68165

P(W=3)=855
