Since each number has a 1/6 probability, law of large number implies you will have about 167 rolls of 1, 2, 3, 4, 5, & 6. The mean of 1, 2, 3, 4, 5, & 6 is 3.5. Therefore, the mean of the dot values will be 3.5.

The expected value is 20 times.
The expected number is 3750.
To determine how many times you would expect to land on 3 after spinning the spinner 20 times, you need to know the probability of landing on 3 in a single spin. If the spinner has an equal number of sections, you can find the probability by dividing the number of sections that include 3 by the total number of sections. Multiply that probability by 20 to get the expected number of times landing on 3. For example, if the spinner has 4 equal sections, the expected number would be (20 \times \frac{1}{4} = 5).
You can expect the spinner to land an odd number 25 times out of 50.
I would expect it to land on a number of 4 or higher 50% of the time or roughly 24 times.
He should expect it 100 times.

The answer depends on the number of sides on the spinner and how they are numbered.
The expected value is 20 times.
The expected number is 3750.

40 times
The expected number of times is the probability x number of throws. Since you have a prob of 1/6 for a seven, then (1/6) * 160 = 26.67 times you would have success. We generally would round up the expected number of successes to the whole number 27.
