Question

In the month of March 2019, Find the days on which the date is a multiple of 5. (see the given page of the calender)

Answer 1

The dates multiple of 5 are 5, 10, 15, 20, 25 and 30.

From the calender, we can observe on these dates, the days fall are Tuesday,

Sunday, Friday, Wednesday, Monday, Saturday

Sample Space = {Tuesday, Sunday, Friday, Wednesday, Monday, Saturday}

∴ n(S) = 6

Hence, the total number days on which the date is a multiple of 5 is 6.
