U is underweight, N is not-underweight a) so you want UUUU = (.18)(.18)(.18)(.18) = .18^4 = .00105 b) wouldn't that be all not-underweight ? or (.82)^4 = .45212 c) at least one underweight implies 1 - Prob(all non-overweight) = 1-.45212 Since there are only 5 cases possible, I...

P=2(W+L) A=WL, so L = 180/W so, P = 2(W+180/W) This is pre-cal, so you don't have calculus at your disposal. But, you do know that a square has maximum area for a given perimeter. So, W = L = √180 = 6√5
