Final answer:
To repeat the display of 'HI' a random number of times between 1 and 10, use a random number generator to determine the repetitions and a for loop to carry out the instruction.
Step-by-step explanation:
Generating Random Numbers and Looping
To repeat a piece of code a random number of times between 1 and 10, you can use a random number generator. Let's say we generate a single random number within the specified range using randInt(1,10). Once we have our random number, we can display 'HI' that many times using a loop. For example, in a programming language like Python, it would look something like this:
import random
repeat_times = random.randint(1, 10)
for _ in range(repeat_times):
print('HI')
In this example, random.randint(1, 10) generates a random number between 1 and 10, and the for loop repeats the instruction to print 'HI' that many times.
