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.

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`}
