Okay, so first of all, we have an experiment, and we have four levels of temperature, five different pressures, and two different catalysts.
00:13
Okay, we have those three variables that we're looking at.
00:19
So first of all, asks to consider all possible combinations how many experiments would need to be conducted.
00:25
And if you just think of this as, like, if you just had two, right? you just had temperature and pressure, well, you'd have to have 20 different ones, right? because you would have the four temperatures, one, two, three, and four, and you'd have the five pressures, and, like, so it would end up, like, you would just have to multiply, right? you do first pressure and first temperature, you'd do first pressure and second temperature.
00:59
Like, you would just have to do all the combinations like that, right? one in three, one in four, one in five, and you would do that, and you would have to end up multiplying.
01:07
So basically, the only thing that you need to do here is just multiply...
