12 packets of salt, each marked 2kg, actually contained the following weights (in kg) of salt:
1.950, 2.020, 2.060, 1.980, 2.030, 1.970, 2.040, 1.990, 1.985, 2.025, 2.000, 1.980
Out of these packets, one packet is chosen at random.
What is the probability that the chosen packet contains more than 2kg of salt?
