To find the probability that a randomly selected customer orders wine, we need to know the total number of customers.
According to the information given, 150 male customers ordered beer, 40 male customers ordered wine, and 20 male customers asked for soft drinks. This means there were a total of 210 male customers (150 + 40 + 20).
Similarly, 38 female customers ordered beer, 20 female customers ordered wine, and 12 female customers asked for soft drinks. This means there were a total of 70 female customers (38 + 20 + 12).
The total number of customers is the sum of male and female customers, which is 210 + 70 = 280.
Therefore, the probability that a randomly selected customer orders wine is 20 (number of customers that ordered wine) divided by 280 (total number of customers), which equals 0.071.
Therefore, the answer is 0.071 or approximately 0.071.
