At bay high school 60% of all students have a car and an ipod and 70% of all students have a car. what is the probability that a student with a car also has an ipod?
a) 10%
b) 68%
c) 86%
d) 93%

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

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=%

Using formula of conditional probability:P(A/B)=

Answer :C)86 %

(d)

step-by-step explanation:

given: the line in the graph passes through points (5,30) and (6,26).

then, the equation of line is:

now, put y=a(n) and x=n,

hence, option d is correct.

no this is a nonlinear negative
