would it be a valid probability distribution or not if the sum does not add to 1

The probability needs to add up to 1

What does the random variable for a binomial experiment of n trials measure?

The random variable measures the number of successes out of n trials

In a carnival game, there are six identical boxes, one of which contains a prize. A contestant wins the prize by selecting the box containing it. Before each game, the old prize is removed and another prize is placed at random in one of the six boxes. Is it appropriate to use the binomial probability distribution to find the probability that a contestant who plays the game five times wins exactly twice? Check each of the requirements of a binomial experiment and give the values of n, r,and p.

Yes. The five trials are independent, have only two outcomes, and have the same P(success); n = 5, r = 2, p = 1/6
