. The list below snows the numbers of each type of music you nave on vour music playes.

Calculate Probability of First Spinner: Calculate the probability of the first spinner landing on a $2$ . There are $4$ equal areas, so the probability is $\frac{1}{4}$ .
Calculate Probability of Second Spinner: Calculate the probability of the second spinner not landing on Move Back. There are $3$ equal areas, and $2$ of them are not Move Back, so the probability is $\frac{2}{3}$ .
Multiply Probabilities for Overall Probability: Multiply the probabilities of the two independent events to get the overall probability. So, $(\frac{1}{4}) \times (\frac{2}{3}) = \frac{2}{12} = \frac{1}{6}$ .
