प्रश्न
A die is thrown. Write the sample space. If P is the event of getting an odd number, then write the event P using set notation.
उत्तर
Since a die is thrown.
Sample Space : S = {1,2,3,4,5,6}
∴ n(s) = 6
Let P = Event of getting an odd number.
P = { 1, 3, 5}
∴ n (P) = 3.

A two-digit number is formed with digits 2, 3, 5 without repetition. Write the sample space
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}`.
If one coin is tossed, write the sample space ‘S’.
Two coins are tossed simultaneously. Complete the following activity to write the sample space and the given events A and B in the set form:
Event A: To get at least one head.
Event B: To get no head.
Activity:
Two coins are tossed simultaneously.
∴ Sample space is
S = `{square, HT, TH, square}`
Event A: To get at least one head.
∴ A = `{square, HT, TH}`
Event B: To get no head.
∴ B = `{square}`
Assertion (A): A die is thrown once and the probability of getting an even number is `2/3`.
Reason (R): The sample space for even numbers on a die is {2, 4, 6}.
