Approximately 9 out of every 50 people who saw a movie this week say they watched it on Netflix. Suppose we want to find the probability that a randomly selected movie-goer saw a movie on Netflix this weekend. Express that probability in three ways: As a fraction, a proportion, and a percentage.

Explanation:

1. As a fraction:

Depart from the definition of probability: probability is the number of favoragle outcomes divided by the total number of possible outcomes:

2. As a proportion:

A proportion is the equality of two ratios. In this case you must set the ratio of people who say they watched it on Netflx, x, per every people who saw a movie this week, 1, equal to the ration 9 /50.

Hence, the proportion that shows the probability is:

Where x is the probability.

3. As a percentage

You just have to multiply the probability by 100:

won't that be plagrisim thought?

step-by-step explanation:

i only know the sequence of arithmetic it adds the first is 5+4 then it goes up as it adds to then it is 9+5 then 14+6 then to 20+7 and so on. 5,9,14,20,27,35.
