To calculate the expected number of times Yvette should expect the spinner to land on 4, you can use the formula for expected value:
\[ E = n \cdot p \]
where:
- \( E \) is the expected number of occurrences,
- \( n \) is the number of spins, and
- \( p \) is the probability of landing on a specific number (in this case, the number 4).
Since the spinner has 5 equal sections, the probability \( p \) of landing on 4 is:
\[ p = \frac{1}{5} \]
Now, if you provide the number of times Yvette spins the spinner (let's say \( n \) spins), you can substitute the values into the formula.
For instance, if Yvette spins the spinner 20 times:
\[ E = 20 \cdot \frac{1}{5} = 20 \cdot 0.2 = 4 \]
If you have a specific number of spins \( n \) in mind, you can substitute that value into the formula to find the expected number of times it lands on 4. Please provide the number of spins if you need a specific calculation!
