Question

1. a. An ordinary six- sided dice is rolled. Calculate the probability

i. of getting a 1 or a 2 _________
ii. of not getting a 1 or a 2 _________
b. What do you notice about your answers in part a?

Answer 1

Part i would be 2/6 or 1/3 (when simplified)

Part ii would be 4/6, or 2/3 (when simplified)

Explanation:

There are a total of 6 possibilities you can get on a six sided dice. So for part i, your chances of getting a 1 or a 2 would be 2/6 (2 numbers you want out of 6 choices).

For Part ii, it's 4/6, because there's 4 numbers you have (3,4,5,6) out of 6 choices, that are NOT 1 or 2.

Both answers in Part A can be simplified to a simpler term. The answers in Part A, we can assume, are Equally likely to happen.

Hope this helps!
