When two six-sided die are rolled, the probability of getting a one on both is 1/36. this means that a) the odds against both die being one are 36 to 1. b) in the long run, the average number of ones is 1/36. c) in the long run the outcome that both die are one will occur on 1/36 of all rolls. d) of every 36 rolls, exactly 1 will have both die be one.

Fluids at rest possess no flow energy. a)- true b)- false

Awall of 0.5m thickness is to be constructed from a material which has average thermal conductivity of 1.4 w/mk. the wall is to be insulated with a material having an average thermal conductivity of 0.35 w/mk so that heat loss per square meter shall not exceed 1450 w. assume inner wall surface temperature of 1200°c and outer surface temperature of the insulation to be 15°c. calculate the thickness of insulation required.
