Question

use the spinner shown to answer the question. assume that it is equally probable that the pointer will land on any one of the colored regions. if the pointer lands on a borderline, spin again. if the spinner is spun once, find the probability that the pointer lands in a red region. the probability that the pointer lands in a red region is (type an integer or a simplified fraction)

Explanation:

Step1: Count total regions and red regions

Total number of regions \( n(S)=8 \). Number of red regions \( n(E) = 3 \).

Step2: Use probability formula

Probability formula is \( P(E)=\frac{n(E)}{n(S)} \). Substitute \( n(E) = 3 \) and \( n(S)=8 \), so \( P(E)=\frac{3}{8} \).

Answer:

\(\frac{3}{8}\)
