<span>There are 4 suit ,, hearts , Diamonds , clubs , Spades
then the 3 cards may be from the 1st OR 2nd OR 3rd OR 4th
<span>p(A)=4*(13C3)/(52C3)=0.0517 Or 5.17%

Answer:
Perimeter will be = 21.6
Step-by-step explanation:
As we know the formula to get the length between two points A and B having coordinates A(x,y) and B (a,b) is
AB = √(x-a)²+(y-b)²
We will use this formula to get the lengths of all sides of the quadrilateral.
AB=√(4+3)²+(2-2)² =√7² =7
BC = √(3-4)²+(-3-2)²=√(-1)²+(-5)² = √1+25=√26 = 5.1
CD = √(3+3)²+(-3-3)² = √6²+(-6)² = √72 = 8.5
DA = √(-3+3)²+(3-2)² =√1 = 1
Since perimeter of the quadrilateral = sum of lengths of all sides
Perimeter = 7 + 5.1 + 8.5 + 1 = 21.6
45% is less than 80. The actual answer is 72. Hope that helps :)
2+4=6
6+-7=-1
Your answer would be negative 1 or -1
