Exercise

Varying the number of trials

In the last exercise you tried flipping ten coins with a 30% probability of heads to find the probability at least five are heads. You found that the exact answer was 1 - pbinom(4, 10, .3) = 0.1502683, then confirmed with 10,000 simulated trials.

Did you need all 10,000 trials to get an accurate answer? Would your answer have been more accurate with more trials?
