Question: If the random variable gives the number of points when a four-sided die is tossed once, determine the expected value E(x), the variance V(r),

If the random variable gives the number of points when a four-sided

If the random variable gives the number of points when a four-sided die is tossed once, determine the expected value E(x), the variance V(r), and the standard deviation . Then repeat in the case that gives the sum when the four-sided die is tossed twice.
