Write the first ten multiples of 3 ,4 and find l.c.m with method

Multiples of 3=3,6,9,12,15,18..

Multiples of 4=4,8,12,16,20..

The first common multiple will be 12

And the next common multiples will be multiples of 12

Hence, first four common multiples of 3,4 are 12,24,36,48

Using the normal distribution principle, the Zscore which corresponds to the area under the normal curve at P(Z < z) = 0.9967 is 2.716

To obtain the Zscore in this scenario, which is the number of standard deviations from the mean value for a given score ; we make use of Zscore calculator or a normal distribution table ;

Using a normal distribution table;

Therefore, the Zscore value is 2.716
