Question

which event is least likely to occur?
answer attempt 1 out of 3
rolling an even number on a twelve-sided die, numbered from 1 to 12.
spinning a spinner divided into four equal-sized sections colored red/green/yellow/blue and landing on blue or yellow or green.
winning a raffle that sold a total of 100 tickets, if you buy 39 tickets.
reaching into a bag full of 4 strawberry chews and 16 cherry chews without looking and pulling out a strawberry chew.

Explanation:

Step1: Calculate probability for die roll

Even numbers on 1-12: 2,4,6,8,10,12 (6 values). Probability: $\frac{6}{12} = 0.5$

Step2: Calculate spinner probability

Favorable sections: 3 (blue, yellow, green). Total sections: 4. Probability: $\frac{3}{4} = 0.75$

Step3: Calculate raffle winning probability

Tickets bought: 39, total tickets:100. Probability: $\frac{39}{100} = 0.39$

Step4: Calculate chew draw probability

Strawberry chews:4, total chews: $4+16=20$. Probability: $\frac{4}{20} = 0.2$

Step5: Compare all probabilities

$0.2 < 0.39 < 0.5 < 0.75$

Answer:

Reaching into a bag full of 4 strawberry chews and 16 cherry chews without looking and pulling out a strawberry chew.
