what is the probability that the random variable x is between 10 and 30?​

Sagot :

Answer:

The Random Variable is X = "The sum of the scores on the two dice". Let's count how often each value occurs, and work out the probabilities: 2 occurs just once, so P(X = 2) = 1/36. 3 occurs twice, so P(X = 3) = 2/36 = 1/18.
