If you have plastic chips that are red on one side and blue on the other, and you drop 8 of them, assuming each chip has an equal chance of landing on either side, the probability of landing red side up is 50%.

Calculation:

• Number of chips dropped: 8
• Probability of red side up per chip: 0.5 (50%)

Expected number of chips landing red side up:

8×0.5=48\times 0.5=48×0.5=4

Answer:

On average, about 4 of the 8 chips would land with the red side up.
