Question

A taste test asks people from Texas and California which pasta they prefer, brand A or brand B. This table shows the results,​

Answer 1

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
