Question

List all events associated with the andom experiment of tossing of two coins. How many of them arc elementary events ?

Answer 1

Since we are tossing two coins
so, the all events associated with random experiment are

{HH}, {HT}, {TH}, {TT}, {HH, HT},
{HH, TH}, {HH, TT}, {HT, TH}, {HT, TT},
{TH, TT}, {HH, HT, TH}, {HH, TH, TT},
{HH, HT, TH, TT},

Total =15

From above the elementary events are
{HH}, {HT}, {TH}, {TT}

Total elementary events = 4
