n = 36/3
n = 12
Answer:
Step-by-step explanation:
Given triangle is a right angle triangle
To find out x we use Pythagorean theorem
where c is the hypotenuse
c=square root (20),
Plug in the values in the formula
Subtract 20 on both sides
Divide whole equation by 2
0=x^2-2x-8
factor the right hand side
Set each factor =0 and solve for x
so
so
The length x cannot be negative, so

<u>Answer:</u>
X and Y are stochastically dependent RVs .
<u>Step-by-step explanation:</u>
Let ,
X = sum of the values that come up after throwing n (≥ 1) fare dice.
Y = number of times an odd number come up.
Let, n = 3
then, P(X =6) = p (say) clearly 0 < p < 1
and P (Y = 3) =
And,
P( X = 6, Y = 3) = 0 ≠
Hence, X and Y are stochastically dependent RVs
Okay so you would have to do
2/3 / 2 and 5/6 3
2/3 / 2 is 1/3
5/6 / 3 is 1/3
So both of them are equal pieces.
