Right.
A thanks i always go to this web site
What was the answer?
1/3;2/3
Correct! The probability of rolling a number less than 3 is 1/3, since there are only 2 possible outcomes: rolling a 1 or rolling a 2, out of a total of 6 possible outcomes. The probability of not rolling a number less than 3 is 2/3, since there are 4 possible outcomes that are greater than or equal to 3: rolling a 3, 4, 5, or 6, out of a total of 6 possible outcomes. Well done!
