ADVICE: an easy way to remember is always remembering them as sine, cos, tan, and using the first letters of each word (ex: opposite) for another word, example, sine= oh hell (opposite/hypotenuse), cos= another hour (adjacent/hypotenuse), tan= of algebra (opposite/adjacent)
We know that there are total 18 socks, and 3 blue pair P(picking pairs of blue sock)= 3/18 or 1/6 As a result, the probability that he will pick a pair of blue socks is 1/6. Hope it help!
