Question

what is the probablity that a letter pucked from the word examination is a constant

Answer 1

Sample Space (S) = 11

Let 'A' be the event of getting a constant
n(A) = 5
p(A) = n(A) / n(s)
= 11 / 5
p(A) = 11 / 5

Answer 2

5/8 is the probability of picking a constant from the word examination.
