According to the Pew Internet & American Life Project, 54% of Internet users have a wireless connection to the Internet via a laptop, cell phone, game console, or other mobile device. Given that users have a wireless, 25% use Twitter to share updates about themselves. What is the probability that an Internet user has a wireless connection and also uses Twitter?

The probability that an internet user uses Twitter and has a wireless connection is 0.135.

Step-by-step explanation:

Given that,

54% of internet users have a wireless connection.

25% use Twitter to share updates, given that the user have a wireless.

Let A be a user who uses a wireless connection.

Let B be a user who uses Twitter.

P(A)=54%=0.54

P(B|A)= 25%=0.25

⇒P(A∩B)=P(A)P(B|A)

⇒P(A∩B)= 0.54×0.25

⇒P(A∩B)=0.135

The probability that an internet user uses Twitter and has a wireless connection is 0.135.

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|
