Question

what is the probability that a spin lands on a space with a number that is at least 4? a $\frac{1}{2}$ b $\frac{5}{8}$ c $\frac{3}{8}$

Explanation:

Step1: Determine total number of spaces

Assume there are 8 spaces (since denominators in options are 8). Total number of possible outcomes \( n(S)=8 \).

Step2: Determine favorable outcomes

Numbers at least 4 are 4,5,6,7,8. Number of favorable outcomes \( n(E) = 5 \).

Step3: Calculate probability

Probability formula \( P(E)=\frac{n(E)}{n(S)} \). Substitute \( n(E) = 5 \) and \( n(S)=8 \), so \( P(E)=\frac{5}{8} \).

Answer:

B. \( \frac{5}{8} \)
