A local brewery in Elmwood, IL is conducting taste tests for new microbrew beers. The brewery prepared four different brews and randomly chose individuals to do a taste test and state which of the four they liked best. Results of the taste test are in the following table:
A 20
B 10
C 40
D 30
Prior to conducting the experiment, it is reasonable to assume preferences for the four brews are equal. What probabilities would you assign to the experimental outcomes prior to conducting the taste test
