Question

If one letter chosen at random from the word 'added' , what is the probability that the letter chosen is a.

Answer 1

Hey there!

Given word = ADDED.

Sample space = { A, D , E }

n(S) = 5

Let the A be the events of letter choosen is A

A = { A }

n(A) = 1 .

Now ,Probability that letter choosen is " a " = P(A) = n(A) / n(S) = 1/5 .

Hope helped!

Answer 2

P(E) of getting alphabet a=No. of favourable outcomes/Total no. of outcomes=1/5
