question
which of these contexts describes a situation that is an equal chance or 50-50?
answer
○ rolling a number less than or equal to 5 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 green or yellow.
○ winning a raffle that sold a total of 100 tickets if you bought 90 tickets.
○ reaching into a bag full of 5 strawberry chews and 15 cherry chews without looking and pulling out a strawberry chew.

Explanation:

Step1: Calculate probability for Option 1

Total outcomes = 6, favorable outcomes (1-5) = 5. Probability: $\frac{5}{6} \approx 0.833$

Step2: Calculate probability for Option 2

Total sections = 4, favorable sections (green/yellow) = 2. Probability: $\frac{2}{4} = 0.5$

Step3: Calculate probability for Option 3

Total tickets = 100, your tickets = 90. Probability: $\frac{90}{100} = 0.9$

Step4: Calculate probability for Option 4

Total chews = 5+15=20, strawberry chews=5. Probability: $\frac{5}{20} = 0.25$

Answer:

Spinning a spinner divided into four equal-sized sections colored red/green/yellow/blue and landing on green or yellow.
