If three different orders are selected, the probability that they are all from restaurant A is 0.0280

What is probability if three different orders are selected, that they are all from restaurant A?

Total order both accurate and not accurate = 1131

Total orders from restaurant A (both accurate and not accurate) = 344

Probability of first order from A = 344/1131

Probability of second order from A = 343/1130

Probability of third order from A = 342/1129

Probability of the first three orders from A = 344/1131 × 343/1130 × 342/1129

Probability of the first three orders from A = 0.0280

Therefore, if three different orders are selected, the probability that they are all from restaurant A is 0.0280
