Answer #1

From the given Probability Mass Function of Y, the following Table is formed:

E(Y) = Σ YiPi = 0.6

pi 0.8

Variance of Y is given by:

s2 = E(уг) _ (E(y) )2-0.8-0.62-0.44

So,

Answer is:

0.44

Let P(RIB1) 2/5 be the probability of selecting a red ball at random from Box 1 which consists of 2 red balls and 3 white balls. Also assume that there is another Box called Box 2 which consists of 1 red ball and 2 white balls. An individual is asked to choose one of the two boxes at random so that PB1)-P(B2)-112. After choosing a box, a ball is selected at random from that box and the ball is observed...

This question is about the Bayes' Theorem. You are given two boxes. Box 1 contains 5 red, 5 green, and 3 blue balls, and Box 2 contains 4 red, 3 green, and 2 yellow balls. You are asked to randomly pick one of the two boxes. Holding that box, you grab one ball at random, and then set the box back down. You found out that it is a red ball. Let A be the event that you choose Box...

A box contains four green balls. We choose balls at random, with replacement, according to the following rules: (i) Upon choosing each ball from the box, we mark it with a red stripe before replacing it in the box. (ii) We stop as soon as we choose a ball with a red stripe (i.e. the ball has been chosen twice). Let x= the number of times that balls were chosen from the box. (Note that x must be at least...

5. Three boxes are numbered 1, 2 and 3. For k 1, 2, 3, box k contains k blue marbles and 5 - k red marbles. In a two-step experiment, a box is selected and 2 marbles are drawn from it without replacement. If the probability of selecting box k is proportional to k, then the probability that two marbles drawn have different colours is 6. Two balls are.dropped in such a way that each ball is equally likely to...
