1. 16/30 or 8/15 ( SIMPLIFIED) because there are 30 pieces.
Four 15 inches + Ten 12 inches = 14
30-14 = 16
So there are 16 8 inch pieces
3. A. 7/20 because 7 pennies ( what you want ) over 20 coins ( 13 dimes + 7 pennies)
B. 13/20
4. Not sure but I think it's 0.75 ( 1.00 - 0.25 )
And 0.05 ( 1.00- 0.95 )
Th total possible outcomes are 6^3 = 216
The possible ways of getting 15 are
555
456
465
546
564
645
654
366
663
636
= 10
so P(sum of 15) = 10/216 = 5/108
