Survey data indicate that 42% of customers at Mega Hit video rental stores subscribe to premium movie channels through their cable television provider. The data also indicate that 31% of MegaHit customers own a DVD player, while 56% of MegaHit customers subscribe to premium movie channels or own a DVD player (or both). What is the probability that a randomly selected Mega Hit customer both owns a DVD player and subscribes to premium movie channels? Write your answer as a decimal (not as a percentage). (If necessary, consult a list of formulas.) xs ?

P=0.17

Step-by-step explanation:

If A and B are dependent events, then we have a Rule of Addition:

Let A represent event that customer at Mega Hit is subscribed to premium movie channels while B represent event that customer at Mega Hit owns a DVD, so, we get the following:

We need to find or probability that a randomly selected Mega Hit customer both owns a DVD and subscribes to a premium movie channels.

Using Rule of Addition, we get:

So, the required probability is 0.17.

0 and 5 minutes

step-by-step explanation:

given that one morning eight buses arrive late by the number of minutes given below:

0 8 2 6 9 2 0 7 8

write these in ascending order

0   0 2 6 7 8 8 9

in the afternoon two more buses arrive at the bus stop say by x and y minutes late.

total number of buses = 10

median = average of 4th and 5th after arranging in ascending order

since 4th entry is 6, the values of x and y should be below 6

also given 0 is the mode so either x or y or both should be 0 because then only 0 gets the maximum frequency and hence mode

thus we have

0 0 0 2 6 7 8 8 9 and another unknown entry which is below 6.

since median is 3.5, we have the unknown entry to be 5 only because then only median =( 2+5)/2

thus the after noon buses were late by 0 and 5 minutes.
