Using probability of independent events, it is found that there is a [tex]\frac{1}{9} = 0.1111[/tex] probability that Michelle’s score is at least 8.
If two events, A and B, are independent, the probability of both happening is the multiplication of the probabilities of each happening, that is:
[tex]P(A \cap B) = P(A)P(B)[/tex]
In this problem:
- Two fair 3-sided spinners are span, and their values are multiplied.
- The only way to get an score of at least 8 is spinning two threes.
- For each spinner, there is a [tex]\frac{1}{3}[/tex] probability of spinning a 3, and the spinners are independent.
Hence:
[tex]P(A \cap B) = P(A)P(B) = \frac{1}{3} \times \frac{1}{3} = \frac{1}{9}[/tex]
There is a [tex]\frac{1}{9} = 0.1111[/tex] probability that Michelle’s score is at least 8.
