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?

Answer:

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
