A discrete variable X can take on integer values of 1 to 10. A sample of size 50 results in the following probability estimates: Xi 1 2 3 4 6 9 10 P(X) 0.2 0.2 0.2 0 0.1 0.2 0.1 Calculate the probability that X is between 6 and 10 inclusive. The probability that X is between 6 and 10 inclusive is K
