Buona serata a tutti; chiedo gentilmente il vostro aiuto per risolvere questo esercizio sulle probabilità: il testo è il seguente . A drawer contains 64 socks. Each sock is one of 8 colours, and there are 8 socks of each colour. If the socks in the drawer are thoroughly mixed and you randomly choose two of the socks, then what is the probability that these two socks will have the same colour?
a) 1/7; b) 1/8; c) 1/9; d) 7/64: e) 9/64
Thanks a lot ; I'm looking forward to receiving lots of answers!
