    What is the probability that the nickel and dime will show heads and the quarter will show tails? \frac {1}{8}

    What is the probability that only one of the coins will show tails? \frac {3}{8}

    Make a table and count the possiblites.

    Hey its easy identify all the possibilties fo all the coins.

    YUU WILL GET

    HHH HHT THH HTT TTT HTH THT TTH

    WHERE H= HEADS N T= TAILS...

    you can see there's only 1 possibility out of 8 that the first two will show tails n d last one a head n the probablity that only 1 coin show tails is 3/8
