Question

homework: unit 4 - mean, median and mode, and probability. question 28, 7.4.21. suppose that the spinner shown is spun once. find the probability of the event that the result of a spin is a, b, c, d, e, f, g, or h. the probability is . (simplify your answer.)

Explanation:

Step1: Identify total outcomes

The spinner has 8 equal - sized sections labeled A - H, so the total number of possible outcomes $n(S)=8$.

Step2: Identify favorable outcomes

The event is getting A, B, C, D, E, F, G, or H. The number of favorable outcomes $n(E)=8$.

Step3: Calculate probability

The probability formula is $P(E)=\frac{n(E)}{n(S)}$. Substituting the values, we get $P(E)=\frac{8}{8}=1$.
