Here is the data to answer the question below:
Short Sleeve:163 that are blue and 295 that are not blue
Non Short Sleeve: 49 that are blue and 123 that are not blue
If 1 student is randomly selected, find the probability of getting someone who did not wear blue or wore a non-shot-sleeve shirt.
Is it [418+172]/630 = 0.9365 or is it [418+49]/630 = 0.7413.
The first answer is my answer. The second is the answer key.
