Question

1- True or false: a. If A is an event of a sample space with P(A)-P(AS), then P(A)-0.5 b. Under certain conditions, it is possible that the sum of the probabilities of all the sample points in a sample space is less than one P(A or B)-P(A)+P(B) P(A and B) P(A).P(B) by its own probability and then adding all the products together; that is P deviation of σ. If x is converted to the standard normally distributed random variable z, c If A and B are any two events of a sample space S, then the addition rule is: d. If A and B are any two independent events of a sample space S, then: e. If two events are mutually exclusive, they are also independent f The mean of a discrete random variable X is found by multiplying each possible value of X g. Two events A and B are said to be independent if P(A and B)= P(A)+p(B) h. Assume that X is a normally distributed random variable with a mean of u and standard then given any three of the values of x, H, a, and z, we can always find the fourth value.

True or False With explanation please.
