Step 1 :Given the total number of individuals is 2448, the total number of individuals who prefer Brand A is 850, the total number of men is 1450, and the number of men who prefer Brand A is 512.
Step 2 :To find the probability that a randomly selected individual prefers Brand A coffee, we divide the total number of individuals who prefer Brand A by the total number of individuals. This gives us \(\frac{850}{2448} = 0.3472\).
Step 3 :To find the probability that a randomly selected individual prefers Brand A coffee, given that the individual is a man, we divide the number of men who prefer Brand A by the total number of men. This gives us \(\frac{512}{1450} = 0.3531\).
Step 4 :Final Answer: a) The probability that they prefer brand A coffee is \(\boxed{0.3472}\). b) The probability that they prefer Brand A coffee, given that a man is selected, is \(\boxed{0.3531}\).
