An ordinary (fair) coin is tossed 3 times. Outcomes are thus triples of "heads" (h) and tails" (t) which we write hth, ttt, etc. For each outcome, let R be the random variable counting the number of tails in each outcome. For example, if the outcome is hhh, then =Rhhh0. Suppose that the random variable X is defined in terms of R
as follows: =XβR2. The values of X are thus:
Value of
X100β1β1β20β1
Calculate the probability distribution function of X, i. e. the function pXx. First, fill in the first row with the values of X. Then fill in the appropriate probabilities in the second row.

Given: p: 2x = 16 q: 3x β 4= 20 which is the converse of p - q? if 2x + 16, then 3x - 4 20. if 3x β4 +20, then 2x # 16. lf 2x = 16, then 3x - 4 = 20. lf 3x β 4= 20, then 2x = 16. o o
