Create a two-way frequency table and determine the probability: 64 people were surveyed at a grocery store about whether they liked regular cheezits or white cheddar cheezits and white milk or chocolate milk. 43 people said they liked regular cheezits, 5 people like both white cheddar cheezits and white milk, and 37 people liked chocolate milk.
Create the frequency table and find P(chocolate milk and not regular cheezits).
See white board for full frequency table.
