Answer:
D. 0.53
Explanation:
California = 90
Total of those who prefer Brand A = 170
To find the percentage, you do:
90/170 × 100 = 52.941...
However you have to round it to two decimal points, hence you do:
52.941 ≈ 53%
53% = 0.53
This is due to 53% representing 53/100 = 0.53
Therefore, the probability that the person that likes brand A is from California is 0.53
