## help123please. 2 years ago Of the student population at a school, 25% owns glasses, and 20% owns contact lenses. What is the probability that a student chosen at ransom will own both glasses and contacts?

@ParthKohli

2. ParthKohli

It's simply the multiplication of both. 25% * 20%

Hmm - thanks. I got 0.05?

4. ParthKohli

Cool stuffz. Write that as a fraction

5. theslytherinhelper

5% or 1/20

5/100?

7. ParthKohli

Yeah, or as thesly said, 1/20

Hmm. Thanks to you both.
