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.

3. 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
