Tutal number of bags is 11. Number of bags containing flour (in kg) more than 6 kg is 7, i.e., 5.05, 5.08, 5.03, 5.06, 5.08, 5.04, 5.07. :. Probability that a bag chosen at random contains more than 5 kg of flour = 7

Question:

Eleven bags of wheat flour, each marked 5 kg, actually contained the following weights of flour (in kg):
4.97,5.05,5.08,5.03,5.00,5.06,5.08,4.98,5.04,5.07,5.00
Find the probability that any of these bags chosen at random contains more than 5 kg of flour.

Solution:

Here Total number of bags=11

Thus total No of events=11

We see that no of bags with weight of more than 5 kgs =7

So favoring events=7

Hence the probability

=Favoring events/ Total events

=7/11

Pl aprove
