defects of mean

If the probability of a defective bolt is 0.05, then find the mean and the standard deviation for the distribution of defective bolts in a total of 400. => 19, 2 0 or 20, 1 9 or 19, 20 or 20, 2 0..

In a factory manufacturing umbrellas, it was found that 90% of packages (containing 100 umbrellas each) did not have any defective umbrellas, 5% contained 1 defective unit each and 3% contained 2 defective units each and 2% contained 3 defective units. Find t..

The sum of the individual masses of various particle in the nucleus must be equal to the nuclear mass. But this is not so in actual practice. The nuclear mass is somewhat less than the sum of the individual masses of various nuclear particles. The difference between the actual nuclear mass an..

Nuclear - Binding energy - The sum of the individual masses of various particle in the nucleus must be equal to the nuclear mass. But this is not so in actual practice. The nuclear mass is somewhat less than the sum of the individual masses of various nuclear particles. The difference between the a..

> is a constant whose value is 1.1 x 10 - 1 5 m. This shows that that heavier nuclei are bigger in size. Density of nuclear matter This value is constant for all nuclei. Binding energy of a nucleus is the energy with which nucleons are bound in the nucleus. It is measured by the work required to be..
