a standard number cure with the numbers 1 through 6 is rolled. find the probability of rolling a number less than 3. find the probability of not rolling a number less than 3.
1/3 ; 2/3
1/2 ; 1/2
5/6 ; 1/2
1/6 ; 5/6
pls help.
To find the probability of rolling a number less than 3, we need to count the number of outcomes that satisfy this condition, which are 1 and 2, and divide by the total number of possible outcomes, which is 6:
Probability of rolling a number less than 3 = (number of favorable outcomes)/(total number of outcomes) = 2/6 = 1/3
To find the probability of not rolling a number less than 3, we need to count the number of outcomes that do not satisfy this condition, which are 3, 4, 5, and 6, and divide by the total number of possible outcomes, which is 6:
Probability of not rolling a number less than 3 = (number of unfavorable outcomes)/(total number of outcomes) = 4/6 = 2/3
