The probability of spinning and landing on red is 20%. meg spins the spinner 25 times and lands on red 10 times, or 40% of the time. she spins the spinner 80 times and lands on red 18 times or 22.5% of the time. what is a good explanation for this?
a) meg miscounted the first time.
b) the spinner broke the second time and didn't land on red.
c) the less trials you do, the closer experimental probability gets to the theoretical probability.
d) the more trials you do, the closer experimental probability gets to the theoretical probability.
