Question

The spinner is spun twice. Two possible outcomes art AC and CA.
a. Create a sample space that lists all of the equally likely outcomes.
b. Refer to the sample space to find the probability of spinning A one or more times in two spins.

Answer 1

a.Any of the three letters can be an outcome in each spin so the sample space is:
AA,AB,AC,BA,BB,BC,CA,CB,CC
b.Check for outcomes that have one or two A’s. There are 5 outcomes that have one or two A’s out of the sample space of 9. So, the probability is:
\(\displaystyle\frac{{5}}{{9}}\)​
