Question

Thirteen out of 20 emails in your inbox are junk emails. What is the experimental probability that your next email is junk?

Answer 1

`P("junk mail") = 13/20`

Explanation:

Experimental probability is determined by actual results, while theoretical probability is determined by maths based on numbers.

The fraction of junk mails so far is `13/20`.

Therefore based on these results, there is a `13 " in "20` chance that the next email will be junk mail. This is the same as the fraction.

`P("junk mail") = 13/20`
