Answer:

W = 2 22/27 lb

Step-by-step explanation:

W = (4 2/3 + 3 7/9)/3

W = (14/3 + 34/9)/3

W = (42/9 + 34/9)/3

W = (76/9)/3

W = (76/27)

W = 2 22/27 lb

Consider the following information about travelers on vacation: 40% check work email, 30% use a cell phone to stay connected to

allsm [11]

Answer:

There is a 40% probability that a randomly selected traveler whochecks work email also uses a cell phone to stay connected.

Step-by-step explanation:

a) What is the probability that a randomly selected traveler whochecks work email also uses a cell phone to stay connected?

The problem states that 40% of the travelers on vacation check work email. And 16% of them check both work email and use a cell phone.

So, the probability is the division of those who use both email and cellphone by those who use email.

$P = \frac{0.16}{0.40} = 0.4$

There is a 40% probability that a randomly selected traveler whochecks work email also uses a cell phone to stay connected.
