What is the probability that a randomly selected car is a two-door hybrid? Express the probability as a percent rounded to the nearest tenth of a percent. Enter your answer in the box. % A two way table with columns titled hybrid, not a hybrid, total and rows titled two door, four door, total. Row 1 hybrid two door 14, not a hybrid two door 5, and total two door 19. Row 2 hybrid four door 7, not a hybrid four door 21, and total four door 28. Row 3 hybrid total 21, not a hybrid total 26, and total total 47.
Accepted Solution
A:
Highlight the "two door" row (row 1) and the "hybrid" column (column 1). The row and column overlap at the cell that has 14 is inside it. This means there are 14 cars that are two doors and they are also hybrids. In other words, there are 14 two-door hybrids.
This is out of 47 cars total (bottom right hand corner)
Divide the two values to get this approximate decimal value 14/47 = 0.29787
Now move the decimal point 2 spots to the right to go from 0.29787 to 29.787%
Finally, round the percentage to the nearest tenth to get 29.8%
