I think someone should check their math before correcting other people's grammar. 1/24 is correct and 5/128 is incorrect. This is a STAAR released question from 2015. It has an answer key. You don't put the penny back!

Reiny · Answer

A 5 cent coin is called a nickel not a Nichol.

10 dimes
5 nickels
1 penny

Prob(dime, then penny)
= (10/16)(1/16)
= 5/128

I recommend that you check your typing, spelling, and grammar in any future posting.
e.g.
bag --> back -->bad

10/16 * 1/15 = 1/24
