Question

Suppose you work in human resources at a tech company and you're hiring four employees to work in IT support.

You're decent at figuring out who would be good at their job: each person you hire has a 70% chance of being good.

Use the binomial distribution function in Excel to determine how likely is it that all four of them are good workers.

Express your answer as a decimal to four places. Include a zero before the decimal point.
