Multiple Choice Answers
Rolling an even number or an odd number on a six-sided die, numbered from 1 to 6.
Spinning a spinner divided into five equal-sized sections colored red/green/yellow/blue/purple and landing on red or green.
Winning a raffle that sold a total of 100 tickets, if you buy 83 tickets.
Reaching into a bag full of 6 strawberry chews and 54 cherry chews without looking and pulling out a strawberry chew.

Answer 1

Compute each probability:

1) Even or odd on a 6-sided die = 1 (certain).
2) Spinner red or green = 2/5 = 0.40.
3) Winning raffle with 83 of 100 tickets = 83/100 = 0.83.
4) Pulling a strawberry from 6 strawberry + 54 cherry = 6/60 = 1/10 = 0.10.

Least likely: pulling a strawberry from the bag (probability 0.10).
