Question

For each of the following, determine whether the given function can serve as the probability mass function of a random variable with the given range: a) f(x) = 2 for r = 1,2,3,4,5, b) f(x) = for x = 0, 1, 2, 3, 4, and c) f(x) = for x = 0,1,2,3,4,5.

Answer 1

Solution :- of the following probability the the as For each determine whether function given can serve function of a Randam variable the given mass range . with - 2 = f(x) = 뜸 1,2,3,4,5 for 돌 리 Z-2 뜸 ㅋ 펴 나2 52 35 3- 커 2-2 쯤 끝 쯤 + ( 글 + t를 +를 + all probability sum The of 내 Here . is놈 to =) ed The But which Not mass Probability at Passible. i8 Not Probability function. a 2 for = 0), 2, 3, 4 b) f= 30 fA AMMS 간 30 NL + 노 30 9 130 06. 30 늚 이 30 = | 30

Sum of all probabilities and all bi 7,0 I Here equal to fw is junction . a valid Probability mass f(2)= 2-0,1,2,3,4,5 - or Here fße) 250 & = 1 = Ś x 6 ala 1.2 Possible. which is Not not a probability mass VL te is function.
