This question is not a direct question, it's more like a confusing question. What has happened doesn't affect the probability of an event that will happen. Here's the hint for you.

OpenStudy (gabylovesyou):

What am I supposed to do to solve this?

Parth (parthkohli):

\(\Large \color{midnightblue}{\rightarrow P(Event) = {\text{Preferred number of outcomes} \over \text{Total number of outcomes}} }\)

Parth (parthkohli):

What do you think now?

OpenStudy (gabylovesyou):

would it be 9/10?

Parth (parthkohli):

Noooo

OpenStudy (gabylovesyou):

mmmmmm

Parth (parthkohli):

You want one number, and total segments are 10. 1/10 = 10% is the probability.

OpenStudy (gabylovesyou):

ohhhhh ok!! The answer is C

Parth (parthkohli):

Yes...

OpenStudy (gabylovesyou):
