I have to write more so ignore this
I think the answer is i D hope this helps
The answer must take into account that the order is irrelevant, that is that it is the same J, Q, K that Q, K, J, and K, J, Q and all the variations of those the three cards.
The number of ways you can draw 50 cards from 52 is 52*51*50*49*48*47*...4*3 (it ends in 3).
,
But the number of ways that those 50 cards form the same set repeats is 50! = 50*49*49*47*....3*2*1
So, the answer is (52*51*50*49*48*....*3) / (50*49*48*...*3*2*1) = (52*51) / 2 = 1,326.
Note that you obtain that same result when you use the formula for combinations of 50 cards taken from a set of 52 cards:
C(52,50) = 52! / [(50)! (52-50)!] = (52*51*50!) / [50! * 2!] = (52*51) / (2) = 1,326.
Answer: 1,326

The slope-intercept form is y=mx+b
, where m is the slope and b
is the y-intercept.
y=mx+b
Reorder −6
and 3x2

Find the values of m
and b using the form y=mx+b
.
m=32
b=−6
The slope of the line is the value of m
, and the y-intercept is the value of b
.
Slope: 32
Y-Intercept: −6
