Q.9. 12 bags of cement, each marked 10 kg, actually contained the following weights (in kg) of cement:
9.5, 10.3, 10.2, 10.1, 10, 10.7, 9.8, 10.4, 9.7, 10.5, 9.7, 9.6
Find the probability that any of these bags chosen at random contains more than 10 kg of cement.

Probability of getting more than 10 kg of cement = 10.3, 10.2, 10.1, 10.7, 10.4 and 10.5
                                                                               = 6/12 = 1/2
Therefore, the probability of getting more than 10 kg of cement is 1/2.
I hope you understand this...
