The spinner has 5 equal sections, which means the probability of landing on any specific number, including the number 5, is \( \frac{1}{5} \).

If Yvette spins the spinner 35 times, the expected number of times it lands on 5 can be calculated as follows:

\[ \text{Expected number of times landing on 5} = \text{Total spins} \times \text{Probability of landing on 5} \]

Substituting in the values:

\[ \text{Expected number of times landing on 5} = 35 \times \frac{1}{5} = 7 \]

Thus, Yvette should expect the spinner to land on 5 approximately 7 times.
