A Bandom Variable is a rule that assigns a number to each outcome of a chance experiment. #2 A coin is tossed 4 times. Let the random variable X denote the # of tails that occur a. List the outcomes of the experiment. (Note: n(S) = 2ª = 16) S = { HHHH, TTTT HHHT, HHTH, HTHH, THHH HHTT, HTTH, TTHH, HTTT, THTT, TTHT, TTTT HTHT, THTH,THHT b. Find the value assigned to each outcome by the random variable X. = 0,1,2,3,4 C. Find the event consisting of the outcomes to which a value of 2 has been assigned by X. X=2 E = { HHTT, HTHT, HTTH, TTHH d. Create a probability distribution of X. 1 4 |P(X = x) NOTE: 0 < P(x;) < 1 and P(x1) + P(x2) + P(x3) +..P(xn) = 1 e. Find a. P(X = 1) = b. P(X > 2) = C.
