2. In a dice tossing random experiment , a red die and a greendie are thrown independently . Consider as a random variable, X,the range in showing dots. for example if the red die is 6 and thegreen die is 4 , then the random variable has a value of 2 in thatexperiment. Calculate the probability, Pr(x=1) =
