Required information 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 2 3 4 6 9 10 P(X) 0.2 0.2 0.2 O 0.1 0.2 0.1 Calculate the probability that X takes the value of 4, 5, or 6. The probability that X takes the value of 4, 5, or 6 is
