Answer:
78 inches or 174 inches (see explanation)
Step-by-step explanation:
If the perimeter is 64 feet, that means that each side is 8 feet, since there are 8 sides (64/8=8). 8 feet is 96 inches (8*12=96). 96-18=78, so the minimum length of wood he needs for the ledges is 78 inches, assuming you're not counting the wood for the perimeter, too (in which case it would be 174 inches) (78+96=174). Hope this helps!
The probability that the machine works in the morning is 50%. This means that out of 100 times it works, it will not overheat 50 times.
The probability that the overheats late if it worked in the morning is 15%. this means that 15% our of the 50 times in the morning when it worked will satisfy this condition, which is 7.5 - so if the machine runs 100 times, it will overheat only in the evening 7.5 times.
The probability that it will overheat only in the evening is 7.5%!
