**Answer:**

C.

**Step-by-step explanation:**

Theoretical probability and Experimental probability are related in that theoretical probability is based on your reasoning (e.g. two sides; therefore, there is a 50% chance of heads), but experimental probability is where your numbers are based off of actual results (e.g. you landed head 1/4th of the time; therefore, there is a 25% chance of getting heads.)

The change in grandpa Ernie's **height** each year is equal to 0.6cm.

As given in the question,

Number of years for which grandpa's** height** is shrinking = 4 years

The total decrease in **height **after four years is equal to 2.4cm.

Let x represents the decrease in **height** each year

The required equation to calculate decrease in **height** each year is given by:

4x = 2.4

⇒ x= 2.4 /4

⇒x = 0.6cm

Therefore, the change in grandpa Ernie's **height** each year is equal to 0.6cm.

The complete question is :

Grandpa Ernie is shrinking over the past four years his height decreased by a total of 2.4 cm it decrease by the same amount each year what was the change in grandpa Ernie’s height each year.
