Answer:
Heat flux is 20 W/m^2
Explanation:
Heat flux (Q) is computed as
where h is heat transfer coefficient and ΔT is the difference between body's temperature
From the interior air to the inner wall
From the the outer wall to the exterior air
The wall is under steady-state condition because heat flux is constant
By using the binomial probability formula, the probability of at least two 3's is equal to 0.1319.
<h3>How to calculate the probability of at least two 3's?</h3>Since the fair cubical die is thrown four times, the number of times is given by n = 4 and the probability of 3's is P = 1/6.
Mathematically, the binomial probability formula is given by:
P(X ≥ 2) = 19/144
P(X ≥ 2) = 0.1319.
