To determine probability for the given data.
Answer to Problem 19PPS
The probability that a student own a MP3 player if he or she also owns CD player is 0.65.
Explanation of Solution
Given information:
43% own a CD player
28% own a CD player and MP3 player.
Let P(CD) = 43% = 0.43
We have to find P(MP3|CD)
We know that,
P(MP3|CD)
Now we put values we get,
Therefore the probability that a student own a MP3 player if he or she also owns CD player is 0.65.
