If X is a random variable that has a chi-squared distribution with two independent count is equal to 3 X that of preaching makes the probability is greater than this value is equal to 0.025.
If X is a random variable with chi-squared distribution is independent of the number 15, find the value of X is greater than the probability that this value is equal to 0.025.
If X is a random variable with a chi-square distribution with the freedom of 15, find the value of X makes more than this value is equal to the probability that 0.025.
