Cоnsider the prоbаbility distributiоn for the rаndom vаriable X X , which represents a single dice roll. X X 1 2 3 4 5 6 P ( X ) P(X) 1 6 frac{1}{6} 1 6 frac{1}{6} 1 6 frac{1}{6} 1 6 frac{1}{6} 1 6 frac{1}{6} 1 6 frac{1}{6} Compute the expected value of X X , and express your answer as a decimal number (not a fraction).  (Recall that we have multiple notations for the expectation: E ( X ) E(X) , μ X mu_X , sometimes X ¯ bar{X} , depending on context.)
