    Total number of elementary events =<nobr aria-hidden="true">50C5</nobr>

    Given,third ticket =30

    => first and second should come from tickets numbered 1 to 29 =<nobr aria-hidden="true">29C2</nobr>

     ways and remaining two in<nobr aria-hidden="true">  20C2</nobr><nobr aria-hidden="true"></nobr>

     ways.

    Therfore, favourable number of events = <nobr aria-hidden="true">29C2*20C2</nobr>

    Hence,required probability = <nobr aria-hidden="true">29C2*20C2/50C5</nobr> =551 / 15134
