ANSWER

A letter is known to have come either from LONDON or CLIFTON.On the envelope just two consecutive letters ON are visible.what is the probablity that the letter has come from （1）LONDON（2）CLIFTON

Posted by Sarita Saini 6 years, 11 months ago

CBSE > Class 12 > Mathematics

1 answers

Gaurav Seth 6 years, 11 months ago

Let E1 --> Letters came from the word LONDON

and E2 --> Letters came from the word CLIFTON

Since the letters have to come from either of these two words

P(E1) = P(E2) = 1/2

Let A --> Two consequitive letters on the envelope are ON

If E1 occurs then the letters ON come from the word LONDON. In this word there are 6 letters in which ON occurs twice. Considering one of the ON's as one object/letter there are now 5 letters.

Therefore

P(A/E1) = 2/5

Now if E2 occurs, then the letters come form the word CLIFTON. In this there are 7 letters in which ON occurs once. Considering ON as one object/letter there are now 6 letters.

Therefore

P(A/E2) = 1/6

Baye's Theorem

(i) P(E1/A) = ( 1/2 * 2/5 ) / ( 1/2 * 2/5 + 1/2 * 1/6 )

---------> = 2/5 * 30/17

---------> = 12/17 ( ans )

(ii) P(E2/A) = ( 1/2 * 1/6 ) / ( 1/2 * 1/6 + 1/2 * 2/5 )

---------> = 1/6 * 30/17

---------> = 5/17 ( ans )
