1. the probability is 0.5 (1/2).
Since the coin can be any one of the 2.
therefore, total sample space = 2
favourable case =1. 2. 3 picks would ensure that we get atleast one pair. 3. take 7L with help of one can.
Then take 7L in that can. Pour 3L in the 3L can.
Give remaining milk in 7L can (4L) to customer.
7+4=11 |
