WebbThe probability of an event can only be between 0 and 1 and can also be written as a percentage. The probability of event A A is often written as P (A) P (A) . If P (A) > P (B) P (A) > P (B) , then event A A has a higher chance of occurring than event B B . If P (A) = P (B) P (A) = P (B) , then events A A and B B are equally likely to occur.

WebbThe probability of observing any single value is equal to $0$ since the number of values which may be assumed by the random variable is infinite. For example, a random variable $X$ may take all values over an interval of real numbers. WebbThe trick is if x is within (0,2) then whether x < y or y > x or equally likely. If x is not withing (0,2) x > y is a certainty. So P = prob (x \le 2)*1/2 + prob (x > 2)*1 = 2/5*1/2 + 3/5*1= 8/10 = 80%.
