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`}
उत्तर
Activity: Let ‘S’ be the sample space when two coins are tossed simultaneously.
∴ S = {HH, HT, TH, TT}
Event A: to get at least one head.
∴ A = {HH, HT, TH}
Event B: to get no head.
∴ B = {TT}.
