Box 1 contains 3 red balls, 5 green balls and 2 white balls. Box 2 contains 5 red balls, 3 green balls and 1 white ball. One ball of unknown color is transferred from Box 1 to Box 2. (a) What is the probability that a ball drawn at random from Box 2 is green? (b) What is the probability that a ball drawn from Box 1 is not white?
Box 1 contains 3 R, 5 G and 2 W
Box 2 contains 5 R, 3 G and 1 W
Let the color of the ball transferred from Box 1 to Box 2 be .
a)The following probabilities are known,
Let the probability of drawing a green ball from Box 2 be represented as .
The following conditional probabilities are known,
Using total probability theorem,
b)Let the probability of drawing a White ball from Box 1 (after transfer) be represented as .
The following conditional probabilities are known,
Using total probability theorem,
The complement (probability of not drawing a White from Box 1) is
