You randomly select 3 socks from a bin of 6 blue socks and 4 black socks. What is probability that all three socks are black if you replace each sock before selecting the next one?

Hello! i hope this
since the cosine is the ratio of the adjacent side to the hypotenuse, you can see that cos 60° = ½. answer. according to the property of cofunctions (topic 3), sin 30° is equal to cos 60°. sin 30° = ½.

None because i don’t know.

8-2x+3x2=6 and six is your answer
