Answer:
20%
Step-by-step explanation:
21/ 105
= 0.2 x 100

Either it is C or D or E.
The volume in cubic meter of the cuboid with the dimensions length = 12 m , breadth = 10m, height = 4.5 m is 540 m³
<h3 />
<h3>Volume of a cuboid:</h3>
where
l =- length
w = width
h = height
Therefore,
l = 12 m
w = 10 m
h = 4.5
v = 12 × 10 × 4.5
v = 120 × 4.5
v = 540 m³

-- The first urn has 9 balls in it all together, and 2 of them are white.
If you don't peek, then the prob of pulling out a white ball is 2/9 .
-- The second urn has 13 balls in it all together, and 3 of them are white.
If you don't peek, then the prob of pulling out a white ball is 3/13 .
-- The probability of being successful BOTH times is
(2/9) x (3/13) = ( 6/117 ) = about 0.0513 or 5.13% (rounded)
