Answer:
C)86%
Step-by-step explanation:
We are given that
Students have a car=60%
Students have a car and Ipod=70 %
We have to find the probability that a student with a car also has an Ipod.
It means we have to find the probability [tex]P(Ipod/car)[/tex]
Probability that a student has a car=0.6
Probability that a student have both car and Ipod=0.7
The probability that a student that a student with a car also has an IPod=[tex]\frac{0.6}{0.7}=\frac{6}{7}\times 100=86[/tex]%
Using formula of conditional probability:P(A/B)=[tex]\frac{P(A\capB)}{P(B)}[/tex]
Answer :C)86 %
