Final answer:
The least likely event to occur is pulling out a strawberry chew from a bag containing 6 strawberry chews and 54 cherry chews, with a probability of 1/10.
Step-by-step explanation:
To determine which event is least likely to occur, we need to calculate the probability of each event and then compare them:
- Rolling an even number or an odd number on a six-sided die: Since there are three even numbers (2, 4, 6) and three odd numbers (1, 3, 5), the probability of rolling either is 3/6 or 1/2. This means you are equally likely to roll an even or odd number each time you roll the die.
- Spinning a spinner divided into five equal-sized sections and landing on red or green: Assuming the spinner is fair, the probability of landing on either red or green is 2/5, since there are two desired outcomes (red and green) and five possible outcomes in total.
- Winning a raffle with 100 tickets if you buy 83 tickets: The probability of winning is 83/100, assuming each ticket has an equal chance of winning.
- Pulling out a strawberry chew from a bag of 6 strawberry and 54 cherry chews: The probability of pulling a strawberry chew is 6/60 or 1/10, as there are 6 strawberry chews in a total of 60 chews.
Comparing the probabilities of each event, the event of pulling out a strawberry chew from the bag is the least likely, with a probability of 1/10.
