The sample space of an experiment is S={a,b,c,d,e,f}. What is the probability of picking a consonant? Write your answer in the simplest fraction form.

There are 6 outcomes in the sample space, in which 4 are consonants (b, c, d, f).

Therefore, the probability of picking a consonant is 4/6, which simplifies to 2/3.

So, the probability of picking a consonant is 2/3.
