Question 1119661
<font color=black size=3>
Greenestamps has the right idea, but made a few typos.


-----------------------------------------

Part (a)


C(4,3)*C(48,2) = 4512 instead of 6768 


The answer should be 4512/(2,598,960) = <font color=red>0.0017</font>


-----------------------------------------
Part (b)


The answer is 1584/(2,598,960) = <font color=red>0.0006</font> (note there are three zeros between the decimal point and the 6; not four zeros)


-----------------------------------------
Part (c)


The answer he wrote for this part is correct.
