If you roll a fair die twice, what is the probability of getting an even number at least once? [will medal]

OpenStudy (anonymous):

how many even numbers are there on a dice

OpenStudy (anonymous):

tell me @tishany

OpenStudy (anonymous):

well there are three 2,4,6 and there are three odds 1,3,5 which means you have a 50 50 chance

OpenStudy (mathmate):

its fine math mate stuff like that happens to me all the time

OpenStudy (mathmate):

Hint for your future problems. When you deal with probabilities of "at least once", you can replace P(at least once) = 1 - P(not even once).

OpenStudy (anonymous):

thank you @cody77445 @mathmate

OpenStudy (mathmate):

@tishany Just sent you a hint for future problems. You could finish the current problem anyway for your self, which is 1-(1/2)*(1/2)
