Let's define the random variable X to be the number of goals scored by a randomly selected team in a randomly selected game. The table below gives the probability distribution of X: 4 5 7 Probability: 0.061 0.154 0.228 0.229 0.173 0.094 0.041 0.015 0.004 0.001 Goals: 0 1 2 3 a. Compute the expected value of the random variable X. E(X)= type your answer..... b. Compute the standard deviation of the random variable X. SD (X)= type your answer..... goals goals 6 8 9
