Simplified
There are 6 numbers on a die. So the probability over all to get either of those 6 numbers is 1/6 if you roll just once. The only number that is odd and less than 3 is 1. 1 is one of those 6 numbers so the probability to get a number odd and less than three in 18 rolls is 3/18 which is also 1/6 if it needs to be simplified
16 1/2= 33/2=66/4
66/4 x 1/4 is 66/16
33/8
The answer is 33/8 ounces.
Im not sure why you said ur wrong b/c i got the same answer
f(x) = -15+ 7
f(x) = -8
