Q. Which of these contexts describes a situation that is unlikely?Rolling a 1 on a standard six-sided die, numbered from 1 to 6.Spinning a spinner divided into four equal-sized sections colored red/green/yellow/blue and landing on red or yellow or green or blue.Winning a raffle that sold a total of 100 tickets if you bought all the tickets.Reaching into a bag full of 19 strawberry chews and 1 cherry chew without looking and pulling out a banana chew.
Rolling a 1 on a die: Analyze the first context - Rolling a 1 on a standard six-sided die, numbered from 1 to 6. The probability of rolling a 1 on a six-sided die is 1 out of 6, or approximately 16.67%. This is a common occurrence in the context of rolling dice, so it is not unlikely.
Spinning a colored spinner: Analyze the second context - Spinning a spinner divided into four equal-sized sections colored red/green/yellow/blue and landing on red or yellow or green or blue.The probability of landing on any one of the four colors is 1 out of 4, or 25%, for each spin. Since the spinner is divided equally and the outcome includes all possible colors, it is certain (100%) that the spinner will land on one of the colors. This is not unlikely.
Winning a raffle: Analyze the third context - Winning a raffle that sold a total of 100 tickets if you bought all the tickets.If you bought all 100 tickets in a raffle, your probability of winning is 100 out of 100, or 100%. This means it is certain that you will win, and therefore it is not unlikely.
Pulling out a banana chew: Analyze the fourth context - Reaching into a bag full of 19 strawberry chews and 1 cherry chew without looking and pulling out a banana chew.Since the bag contains only strawberry and cherry chews, there are no banana chews in the bag. Therefore, the probability of pulling out a banana chew is 0 out of 20, or 0%. This is an impossible event given the contents of the bag, making it highly unlikely.
