At a local bar in a small Midwestern town, beer and wine are the only two alcoholic options. The manager noted that of all male customers who visited over the weekend, 150 ordered beer, 38 ordered wine, and 18 asked for soft drinks. Of female customers, 37 ordered beer, 20 ordered wine, and 10 asked for soft drinks.
Construct a contingency table that shows frequencies for the qualitative variables Gender (male or female) and Drink Choice (beer, wine, or soft drink).

Solution
given
At a local bar in a small Midwestern town, beer and wine are the only two alcoholic options. The manager noted that of all male customers who visited over the weekend, 150 ordered beer, 38 ordered wine, and 18 asked for soft drinks. Of female customers, 37 ordered beer, 20 ordered wine, and 10 asked for soft drinks.
A) table
B) we have to find the probability that a customer orders wine P(W)
since total number of customer that orders wine are 58
total number of customers=273
hence P(W)=58/273=0.2124
C) we have to find probability that a male customer orders wine that is P(W|M)
P(W|M)=P(W Intersection M) / P(M)
=38 / 273/206/273=38/206=0.1845
D)we have to check the events
