Two pupils each estimate the probability that a drawing pin lands point up. One drops the pin 20 times and the other drops it 1000 times. Select all statements that are true about their estimates. Select all that apply.

Explanation

A larger number of trials averages out the swings that a handful of results can produce, so the estimate from 1000 drops is expected to sit closer to the true value than the estimate from 20 drops. The belief that a result becomes due after a run without it is a separate mistake, because each drop is unaffected by the drops before it and nothing about the past raises the chance of the next one.
