Stephen read 121212 books, 202020 magazines, and 171717 newspaper articles last year. Based on this data, what is a reasonable estimate of the probability that Stephen's next reading material is a magazine?

41%

Step-by-step explanation:

So you need to find the probability first:

12+20+17=49

There are 20 magazines:

20/49=0.4081

That rounded would be 0.41.

Now you need to get rid of the decimal point:

0.41×100=41

41%

Hope this helped!
