3 is an odd number, so we need an even number of sets of 3 cards because 18 is an even number.
So we need 0, 2, 4 or 6 sets of three.
0 2-card + 6 3-card, 3 2-card+4 3-card, 6 2-card+2 3-card, 9 2-card+0 3-card. There are only 4 combinations:
(2-card, 3-card)=(0,6), (3,4), (6,2), (9,0).

Verify that the following function is a cumulative distribution function.

SOVA2 [1]

Answer:

Following are the answer to this question:

Step-by-step explanation:

In the given equation there is mistyping so, correct equation and its calculation can be defined as follows:

Given:

$f(x) =\left\begin{array}{cc} 0&x< 1\\0.5& 1 < x$

Calculated value:

$1) \ \ P(x < 3) =1\\\\2) \ \ P(x < 2) = 1-0.5 \\$

$= 0.5$

$3) P(1 < x < 2) = P( x< 2) -p(x< 1)\\\\$

$=0.5-0\\=0.5\\$

$4) \ \ P(x> 2)= 1-P(x$

$=1-0.5\\=0.5\\$

That's why the given equation is true.
