Random variables can also be defined in terms of their cumulative distribution function, or, equivalently, P(X ? For example, if you tossed a coin in the air there is zero probability of the coin remaining in the air forever. Which probability category is defined as the observed relative frequency with which an event occurs? The reason for doing this, is that P(small) = (1/26 [chance of getting the letter correct, which implies you win regardless] - 1/2600 [the chance of getting the grand prize, since 1/26 as the first value, implies that you could also win the grand prize] ) So one way to think about it We randomly ask four adults whether they have a college degree. 13. winning numbers are 3, 15, 46, and 49?
