A fair die is rolled. Find the probability that the number obtained is not greater than 4.
Of the 6 numbers that can come up 4 of them (1,2,3, and 4) are not greater than 4. The probability of that happening = 4/6 =
What is the probability of getting a number greater than 4 in a die?
Hence, probability of getting a number greater than or equal to 4=n(E)/n(S)=3/6=1/2.
What is the probability of drawing a number greater than 4?
Number greater than 4 are 5 and 6 . So required probability is 26=13.
What is the probability of rolling a sum greater than 4?
Therefore, the probability that the sum is 4 or higher is 11/12.
