Flip a coin twice The sample space of possible outcomes is H

Flip a coin twice. The sample space of possible outcomes is

Solution

If two coins tosses, Let A be the event that 1st toss give and B  be the event that 2nd toss give.

so A and B can be,

A={H,T}

B={H,T}

so in the combine case the possible sample space is,

A*B={HH,HT,TH,TT}
