A number cube with the numbers 1 through 6 is rolled. Find the given probability.
P(number<2)
A.) 1/6
B.) 2/6
C.) 4/6
D.) 3/6
P(number ≥3)
P(complement of 4)
A.) 1/6
P(number ≥3) = 1 - P(number <3) = 1 - P(number = 1 or number = 2) = 1 - (1/6 + 1/6) = 1 - 2/6 = 4/6
P(complement of 4) = 1 - P(number = 4) = 1 - 1/6 = 5/6
