Three coins are tossed together find the probability of getting one head and two tail

Dear Student,

Please find below the solution to the asked query:

We show sample space when three coins are tossed :

We know , Probability P ( E )  = Total number of desired events n ( E )Total number of events n ( S )


n ( S ) =  8

Events where we get one head and two tail = { H,T,T} , {T,H,T} and {T,T,H} , So

Number of events where we get one head and two tail = 3 , So

n ( E ) = 3


Probability of getting 1 head and 2 tail  = 38                                           ( Ans )
