4:52 0 46 | | - 62% X Problem 3 Suppose you are customising a character in your favourite video game, and the character has four traits: brains, strength, charisma, and fun. You distribute fifteen points between these four traits, subject to the condition that each trait has at least one point and no more than five points. 1. How many ways are there to customise your character? Let X be the brains score of a character chosen uniformly at random out of the pool of possible characters. What is P(X-3)? Let Y be the sum of the four trait scores for a character chosen uniformly at random out of the pool of possible characters. What is E(Y)? |||

4:52 20 ← to 5 for this problem. Step2 b) 2) It is given that X denotes the brain score of a character chosen uniformly at random. 62% - ا ا 46 0 Also, it is provided that each trait has at least 1 point and no more than 5 points. Thus, it can be said that X follows a uniform distribution with 1 and 5. That is, X-U(1, 5) The probability distribution of Xis as follows: P(X = x)=5−1+1, x = 1, 2, 3, 4, 5 =-=- Step3 c) Thus, the probability of P(X = 3) is calculated as follows: P(X = 3)=, as x = 3 =0.20 _ ||| VX Do
