14% of all cell phone users use their phone for internet access. in a random sample of 10 cell
phones, what is the probability that exactly 2 have used their phones to access the internet?

if number of useres are take to be 100(example)

Step-by-step explanation:

total users=100

14% of total users=14

therefore probability=14/100

new probabiltity=(14/100)*(2/10)

first option

a function is a relation in which an input is paired with exactly one output.

so, let's find the right answer.

in our first option, our inputs are january, february, and march. the outputs are 30, 28, and 25. each input has it's own output. this is correct!

our second option we know is incorrect, because ms. valverade has two outputs, dogs and cats. this is not a function.

our third option is incorrect as well. the yellow square has two ouputs, the square and the triangle.

lastly, in our fourth option, we see the number 7 two times with a different output. therefore, this is not a function.

remember: each input must be paired with only one output!

the answer is 0.071

good luck! : d
