what is the probability that a random point on $overline{ab}$ will be on $overline{cd}$?\nenter as a decimal rounded to the nearest hundredth.
Answer
Explanation:
Step1: Calculate length of AB
$AB=70 - 30=40$
Step2: Calculate length of CD
$CD=65 - 35 = 30$
Step3: Calculate probability
$P=\frac{CD}{AB}=\frac{30}{40}=0.75$
Answer:
$0.75$
