Question

5. A box contains pairs of socks of two colours
(black and white). I have picked a white
sock. I will pick out one more with my eyes
closed. What is the probability that it will
make a pair?
​

Answer 1

Answer:

1/3

Step-by-step explanation:

Total no. of outcomes = 4 - 1 = 3

No. of favourable outcomes = 1

P (E) = No. of favourable outcomes / Total no. of outcomes

∴ P (making a pair) = 1/3
