A drawer contains two pairs of red socks, three pairs of yellow socks, and one pair of black socks. One sock is taken from the drawer and put back after checking its color. A second sock is then taken out. What is the probability that the first and the second are yellow?​

C) 1/4

Step-by-step explanation:

P(Y,Y) = 3/6 x 3/6 = 1/2 x 1/2 = 1/4

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).
