If we draw the contingency table of x (vertical) against y (horiz.), we have a square.
For n=4, we have (legend: < : x<y = : x=y > : x>y
y 1 2 3 4
x
1 = < < <
2 > = < <
3 > > = <
4 > > > =
We see that there are n(n-1)/2 cases of x<y out of n^2.
Therefore,
p(x<y)=n(n-1)/(2n^2)=(n-1)/(2n)
However, if the sample space is continuous, it will be simply p(x<y)=1/2.
Answer:
g = 3.5
f = 78°
<u>Finding</u><u> </u><u>g</u><u>:</u>
25 is parallel to 8g - 3, so they are equal to each other.
25 = 8g - 3
28 = 8g
g = 3.5
<u>Finding</u><u> </u><u>f</u><u>:</u>
72° create a sum of 180° when adding to (f + 30) because they are supplementary.
72 + f + 30 = 180°
102 + f = 180°
f = 78°
Hope this helps!
Answer:
Let selling price of three-piece suit = x. Applying 7% sales tax, total amount paid = x + xx7 - $152.79. 100 207 100 ०१ This is the $ 152.79 os, x- $142.7943 price after marked down of 40%, let the regular price of three-piece suit be = y. Therefore y [ 3 - 4m] $342.1943 1 - - $237.99 Regular price of 1 piece suit $ 237.99
