Question

(2) Each card bears one letter from the word "PROBABILITY' The cards are
placed on a table upside down. Find the probability that: (i) a card drawn
bears the letter 'B'. (ii) a card drawn bears a vowel.​

Answer 1

Answer:

sample space be 'S'

S = { P , R , O , B, A , B, ,I, L,I,T,Y }

n(S) = 11

I) Let A be the the event that the card drawn bears letter 'B'

A = { B , B } n(A) = 2 P(A)= n(A)/n(S) = 2/11

ii) Let B be The event that the card drawn bears a vowel .

B = { O , A , I , I }

n(B) = 4. P(B) = n(B)/n(S) = 4/11

i)2/11 ii) 4/11

Hope this helps you and this chapter is very easy if you understand the concepts well ...
