SAT math scores are normally distributed with the parameters below. μ=500σ=100μ=500σ=100 What is the probability a randomly selected score is more than 460 points                           ["", "", "", "", ""]            What score separates the lowest 20% of scores from the rest?

Is the following distribution a probability distribution? (x, P(X)) = (-2,1.23); (-1, 0.15) ; (0, -1.20); (1, 0.52); (2, 0.30) There are five ordered pairs:  X values and their probabilities for example  P(1) = 0.52.   X -2 -1 0 1 2 P(X) 1.23 0.15 –1.20 0.52 0.30
