#P(S) = 2/10 = 1/5#

Explanation:

This is a one event probability.

#"Probability"= ("number of desirable outcomes")/("total number of possible outcomes")#

There are 2 silver marbles in a bucket with 10 marbles altogether.

#P(S) = 2/10 = 1/5#

A Probability is always a value from 0 to 1.
It is usually given as a fraction in simplest form, but may also be expressed as a percentage or a decimal.

#2/10 = 1/5 = 20% = 0.2#
