Adealer dealt the following cards from a shuffled deck:

3 , 2 , 2 , a , k , q , k , 5 , 2 , 6
4 , 5 , k , 2 , 7 , 6 , a , j , j , a

what was the experimental probability of dealing a black card?

can someone will give medal 8 cards are black and12 are red plesseee do i divide 20 by 8 or 8 by 20,

Well we know that there are 20 cards as given by the equation. And there are 8 black cards.

8/20= .40 or 40% the answer for me is C. 40%

p ÷ r = tan(x)

step-by-step explanation:

given that there is a figure below shows a right triangle: a right triangle is shown with hypotenuse equal to q units and the length of the legs equal to p units and r units.

graph is missing so i will create the graph as per given information.

the angle between the legs having lengths p units and q units is y degrees. the angle between the legs having lengths r units and q units is x degrees.

now we need to find about what is p ÷ r equal to.

so we can use trigonometric ratio tan(x)=[altitude]/[base] to find the value of p ÷ r, because p is the altitude and r is the base.

p ÷ r=tan(x)

hence final answer is p ÷ r=tan(x).
