brokerage survey reports that 32% of all individual investors have used a discount broker (one that does not charge the full commission). If a random sample of 85 individual investors is taken, approximate the probability that at most 24 have used a discount broker. Use the normal approximation to the binomial with a correction for continuity. Round your answer to at least
