It will be right angle triangle. The two vectors beginning at the same vertex
of a triangle are <2,3> and <-3,2> is classified as right-angled
triangle. It is classified as a right-angled triangle because the dot product
of the vectors are 0.
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!
