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)
Solution
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.

Two coins are tossed simultaneously. Complete the following activity of writing of the sample space (S) and expected outcomes of the events :
1) Event A : to get at least one head.
2) Event B : to get no head.
Activity : If two coins are tossed simultaneously
∴ s = {`square , "HT","TH", square`}
1) Event A : at least getting one head.
∴ A = {`"HH" , square , "TH"`}
2) Event B : to get no head.
∴ B = {`square`}

Two coins are tossed simultaneously. Write the sample space (S) and expected sample points in the given events by completing the activity.
- Event A: to get at least one head.
- Event B: to get no head.
Activity: Let ‘S’ be the sample space, when two coins are tossed simultaneously.
∴ S = `{square, HT, TH, square}`
i. Event A: to get at least one head.
∴ A = `{HH, square, TH}`
ii. Event B: to get no head.
∴ B = `{square}`.
