Total checkers = 2 + 6 = 8
P(black, then red) = (6/8)(2/7) = 3/14
Answer: 3/14
You refer to a rectangular distribution.
I.e. Area ∝ probability
so, length x height = area
=> 6 x height = 1
so, height = 1/6
Therefore, greater than 2.25 minutes => 8-2.25 = 5.75 minutes
=> 5.75 x 1/6 = 0.9583
Since this is uniformly distributed, there is no need to
find the height or standard deviation.
Answer:
4). 
Step-by-step explanation:
The Given expression is that,
On simplifying,
= 
= 
= (2×2×2) × (
× × )
=
Thus, <u>option 4</u> i.e. is the correct simplification of the given expression.
X² + x + ...m
x² + x + 1/4
\/x² = x
\/(1/4) = 1/2
2*x*1/2 = 2x/2 = x
x² + x/2 + 1/4
4 + (6-1)d = 179
<span>4 + 5d = 179 </span>
<span>5d = 175 </span>
<span>d = 35</span>
