Answer:

Explanation:

The last context is certain.

There is a 1 out of 6 probability in rolling a six on a six sided die.

There is zero probability for the second and third.

However, you will choose either strawberry or cherry from the bag without looking. The bag has no other options.

Answer:

Reaching into a bag full of 10 strawberry chews and 10 cherry chews without looking and pulling out a strawberry or a cherry chew.

Explanation:

Which of these contexts describes a situation that is certain?

We’re looking for a situation that is certain.

Rolling a number less than or equal to 5 on a standard six-sided die, numbered from 1 to 6.

Within that set of 6 outcomes, there are 5 possible ways of rolling a number less than or equal to 5: {1, 2, 3, 4, 5}. 5 out of 6 is significantly more than half. When something may occur significantly more than half the time, but not all the time, we say it is likely.

Incorrect.

Spinning a spinner divided into four equal-sized sections colored red/green/yellow/blue and landing on white.

Within the set of 4 possible outcomes, there are 0 ways of landing on white. 0 out of 4 is 0. When there is no way for something to occur we say it is impossible.

Incorrect.

Winning a raffle that sold a total of 100 tickets if you bought 0 tickets.

Within the set of possible outcomes, there are 0 ways of winning if you bought 0 tickets. 0 out of 100 is 0. When there is no way for something to occur we say it is impossible.

Incorrect.

Reaching into a bag full of 10 strawberry chews and 10 cherry chews without looking and pulling out a strawberry or a cherry chew.

Within the set of 20 possible outcomes, there are 20 possible ways of pulling out a strawberry or a cherry chew. 20 out of 20 is 1. When something will occur all the time, we say it is certain.

Correct!

The correct answer is: Reaching into a bag full of 10 strawberry chews and 10 cherry chews without looking and pulling out a strawberry or a cherry chew.
