Hey there! A dozen rolls = 12 rolls, of means multiply, we are going to multipy 3/4 by 12, make 12 a fraction, 12=12/1. Now, we can multiply 3/4 by 12/1. 3/4×12/1=36/4. Simplify 36/4 to 9. So, Raymond bought 9 rolls.

There are 12 rolls in a dozen.
1/4 of a dozen is 3, 2/4 is 6, so essentially 3/4 would be 9

A suitable probability calculator can show you this answer.

_____

The z-values corresponding to the build time limits are ...

z = (37.5 -45)/6.75 ≈ -1.1111

z = (54 -45)/6.75 ≈ 1.3333

You can look these up in a suitable CDF table and find the difference between the values you find. That will be about ...

0.90879 -0.13326 = 0.77553

The probability assembly will stay on schedule is about 78%.
