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?

It is given that

Total number of salt packets = 12

Number of packets having more than 2kg of salt = 5

We know that

Probability that the chosen packet contains more than 2kg of salt = number of packets having more than 2kg of salt/ total number of salt packets

By substituting the values

Probability that the chosen packet contains more than 2kg of salt = 5/12
