can someone help me with this question god bless them

Check my work 16 Three tables listed below show random variables and their probabilities. However, only one of these is actually a probability distribution. 10 A B C points X P(x) X P(x) X P(x) 25 0.1 25 0.1 25 0.1 50 0. 2 50 0.2 50 0.2 75 0.4 75 0.4 75 0.4 100 0.3 100 0.5 100 0.7 eBook a. Which of the above tables is a probability distribution? References A b. Using the correct probability distribution, find the probability that x is: (Round the final answers to 1 decimal place.) 1. Exactly 25 = 2. No more than 75 = 3. More than 75 = 0.3 c. Compute the mean, variance, and standard deviation of this distribution. (Round the final answers to 2 decimal places.) 1. Mean 2. Variance o2 3. Standard deviation o Mc Graw Hill
