      Can anyone help me with this question?

      When Jack wakes up everyday, he picks a sock. There is 1 blue sock, 2 white socks, 3 red socks, and 4 yellow
      socks. Because Jack is biased in his pick, the probability of him picking out a blue sock is 4 times as likely as
      a yellow sock, 3 times as likely as a red sock, and 2 times as likely as a white sock. What is the probability of
      him picking a yellow or white sock?

          Unfortunately I don't have the answers with me. This is a practice test.

            @superdog I'm getting half, but it appears, on the test doc, that half isn't an answer choice, so I'm not sure anymore...

            If you see the text messages between two programmers, here are some common acronyms to know:
            imo: iteration may overload
            brb: bad recursion brb
            rofl: right-oriented frame layout

              The probability of Jack picking a yellow or white sock is 0.6 (60%).

              The probability of Jack picking a blue sock is 4/14 (28.6%)

              The probability of Jack picking a red sock is 3/14 (21.4%)

              The probability of Jack picking a white sock is 2/14 (14.3%)

              The probability of Jack picking a yellow sock is 1/14 (7.1%)

              Therefore, the probability of Jack picking a yellow or white sock is 0.6 (60%)
