If a single letter is drawn from the set {m,a,t,h,e,i,c,s}

Question

what is the probability that the letter drawn is a member
of the set {m,a,t,h}

Answer 1

Possible outcomes = 8
succesful outcome = 4
P({m,a,t,h}) = ?

Answer 2

number of possible outcomes = 8 (one for each letter)
number of successful outcomes = 4
P({m,a,t,h}) = ?
