Use combination
There are 4 queen cards in a deck of 52 cards
Probability = 4C2 / 52C2

I calculate 4C2 first
4C2 = 4! / (2! 2!)
4C2 = (4 × 3 × 2 × 1) / (2 × 1 × 2 × 1)
4C2 = 6

Then I calculate 52C2
52C2 = 52! / (50! 2!)
52C2 = (52 × 51)/2
52C2 = 1.326

Hence, the probability is
Probability = 4C2 / 52C2
Probability = 6/1,326
Probability = 1/221

t6 = 6 * (-4)^5
t6 = 6 * (-1024)
t6 = -6144

PLS HELP AND ANSWER QUICK
Greeley [361]

Answer:

ACB=44°

DCE=35°

BCD=101°

Step-by-step explanation:

ACB is a triangle and all triangles are 180 degrees

78+58=136

180-136=44

DCE is also a triangle

85+60=145

180-145=35

a straight line is 180 degrees, we already know what the other two is.

35+44=79

180-79=101

Viktor [21]
Any equilateral triangle has 3 angles of 60° each as all the angles have to add to 360° and there must be 3 equal sides. As no side length is specified you can make infinitely many different equilateral triangles provided they all have different side lengths.
