To determine which event is most likely to occur, let's analyze each option:
-
Rolling a number greater than or equal to 3 on an eight-sided die: The possible outcomes are 1, 2, 3, 4, 5, 6, 7, and 8. The numbers that are greater than or equal to 3 are 3, 4, 5, 6, 7, and 8. That's 6 favorable outcomes out of 8 total outcomes. The probability is \( \frac{6}{8} = \frac{3}{4} = 0.75\) or 75%.
-
Spinning a spinner divided into four equal-sized sections colored red/green/yellow/blue and landing on brown: There is no brown section on the spinner. Therefore, the probability is 0%.
-
Winning a raffle that sold a total of 100 tickets, if you buy 90 tickets: If you have 90 out of 100 tickets, the probability of winning is \( \frac{90}{100} = 0.9\) or 90%.
-
Reaching into a bag full of 8 strawberry chews and 52 cherry chews without looking and pulling out a strawberry chew: There are a total of 8 + 52 = 60 chews. The probability of pulling out a strawberry chew is \( \frac{8}{60} = \frac{2}{15} \approx 0.1333\) or about 13.33%.
Now, comparing the probabilities:
- Rolling a number greater than or equal to 3: 75%
- Landing on brown: 0%
- Winning the raffle: 90%
- Pulling out a strawberry chew: approximately 13.33%
The event that is most likely to occur is winning a raffle that sold a total of 100 tickets, if you buy 90 tickets with a probability of 90%.
