Quizplus · Accepted Answer

The expected value of the probability distribution is calculated by multiplying each possible outcome by its probability and then summing those products. Therefore, Expected value = (0*0.2) + (1*0.3) + (2*0.35) + (3*0.1) + (4*0.05) = 2.35. Therefore, the expected number of goals per game is 2.35, which is option D.
