growth of a particular type of plant. He is testing the effects of four growth factors: lighting, age, temperature, and humidity. Here are the levels he's testing for each

Respuesta :

The level of each growth factor is an illustration of a combination

There are 90 ways of combining one level from each growth factors

How to determine the number of combinations?

From the complete question (see attachment), we have the number of levels in each growth factor is:

Lighting = 3

Age = 5

Temperature = 2

Humidity = 3

So, the number of combination (n) is:

n = 3 * 5 * 2 * 3

n = 90

Hence, there are 90 ways of combining one level from each growth factor.
