Question

What is the probability of the complement of rolling a number less than 5 by using a six-sided die?

Answer 1

Answer:

1/3

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

A probability of the complement of an event is 1 subtracted by the probability of the event.

Probability of rolling a number less than 5:

6 numbers(from 1 to 6), of which 4(1,2,3,4) are less than 5. So

p = 4/6 = 2/3

Probability of the complement of rolling a number less than 5:

1 - 2/3 = 1/3

So 1/3 is the answer
