The area of the dock is 20ft
24 = 2/1/2 cups
1 cup = 9/3/5
30 = 3/1/8 cups
Answer:
.74
Step-by-step explanation:
First, you know that 30% are boys and 70% are girls. Then, take 60% of 30% and 70% of 80%. From there you get .74 as the probability of a randomly chosen child having taken a car to school.
