Answer:
30
Step-by-step explanation:
We require to calculate the volume of 1 brick
V = lbh ( l is length, b is breadth and h is height ), that is
V = 14 × 8 × 5 = 560 cm³
Now divide the volume of concrete available by the volume of 1 brick.
number of bricks made = 
= 30

Answer:
As a fraction, the answer is exactly 86/969
In decimal form, the answer is approximately 0.08875
=====================================================
Work Shown:
The assumption is that no replacements are made for each selection.
5 red, 6 blue, 8 green
5+6+8 = 19 total
A = P(3 red) = (5/19)*(4/18)*(3/17) = 10/969
B = P(3 blue) = (6/19)*(5/18)*(4/17) = 20/969
C = P(3 green) = (8/19)*(7/18)*(6/17) = 56/969
D = P(3 all same color)
D = A+B+C
D = 10/969 + 20/969 + 56/969
D = (10+20+56)/969
D = 86/969
D = 0.08875
There is no whole number that is half of 11 but the half number is 5.5
