Question

You choose a marble at random from a bag containing eight brown marbles, six yellow marbles, and one purple marble. You replace the marble and then choose again. Find the probability

Answer 1

P ( both yellw ) =  ( 6/ 15 ) * ( 6/15)  = 4/ 25

P ( both purple) = ( 1/ 15) * 1/15  = 1/ 225

P  Brown and Purple = ( 8/ 15 ) * ( 1 / 15)   = 8/225

P ( yell then brown ) = ( 6/15  *  8/15  = 16 / 75
