Question: The probability function f of the variable X is defined by Then, the value of c is (a) 955 (b) 5536 (c) 3655 (d) 559

The probability function f of the variable X is defined by1/8, if x = 1, f(x)=cx/16, if x = 2,3, or 4,

Then, the value of c is

(a) 9∕55

(b) 55∕36

(c) 36∕55

(d) 55∕9

(e) 16∕55

1/8, if x = 1, f(x)=cx/16, if x = 2,3, or 4, 1/64, if x = 5.
