Multiple choice

A bag contains $7$ black socks, $12$ white socks, and $17$ red socks. If you pick one sock at random from the bag, what is the probability that it will NOT be white?

  1. $\dfrac {1}{2}$
  2. $\dfrac {2}{3}$
  3. $\dfrac {3}{4}$
  4. $\dfrac {7}{12}$
  5. $\dfrac {7}{36}$
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Total socks = 7 + 12 + 17 = 36. The number of non-white socks is 7 (black) + 17 (red) = 24. The probability is 24/36, which simplifies to 2/3.

AI explanation

The total number of socks in the bag is 7 black + 12 white + 17 red = 36. The number of socks that are not white is 7 + 17 = 24. Using the basic probability formula, the probability of picking a sock that is not white is 24 / 36, which simplifies to 2/3.
