A shipment of 10 microwave ovens contains 3 defective units. A restaurant buys four of these units. What is the probability of the restaurant buying at least three nondefective units? The probability of the restaurant buying at least three nondefective units is nothing. (Round to three decimal places as needed.)
Added by Enrique W.
Step 1
Given that there are 7 nondefective units out of 10 total units, the probability of choosing 3 nondefective units out of 4 can be calculated using the combination formula: \[ P(\text{3 nondefective units}) = \frac{{\binom{7}{3} \times Show more…
