Answer» Correct option is (B) 1/7 Last day of a month can be any of 'Sunday, Monday, Tuesday, Wednesday, Thursday, Friday and Saturday'. \(\therefore\) Total outcomes is n(S) = 7 The favourable outcomes for the event that "the last day of a month is Sunday" is only Sunday. \(\therefore\) Number of favourable outcome is n(E) = 1 \(\therefore\) The probability of "the last day of a month is Sunday" is \(P(E)=\frac{n(E)}{n(S)}=\frac17.\) Correct option is B) 1/7

The probability of “the last day of a month is Sunday” A) 2/7B) 1/7C) 3/7D) 4/7

Answer»

Correct option is (B) 1/7

Last day of a month can be any of 'Sunday, Monday, Tuesday, Wednesday, Thursday, Friday and Saturday'.

\(\therefore\) Total outcomes is n(S) = 7

The favourable outcomes for the event that "the last day of a month is Sunday" is only Sunday.

\(\therefore\) Number of favourable outcome is n(E) = 1

\(\therefore\) The probability of "the last day of a month is Sunday" is \(P(E)=\frac{n(E)}{n(S)}=\frac17.\)

Correct option is B) 1/7
