this is a tricky question, in part because the prompt is making you think about the conditions needed to stop rolling the die, but the program code you're filling in defines the conditions needed in order to roll the die.
this is because we're filling in the missing code on the while loop that is simulating the rolling of the die. we have to ask:
what are the conditions needed in order to keep rolling the die? based on the prompt, we want to keep rolling the die as long as the number of rolls is under 100 and the number of 6's is under 25. if either of those conditions isn't true, we will exit the loop. for example, if we imagine that we're on our 100th roll and our 20th time rolling a 6, the conditions in the while loop would be:
100 < 100 && 20 < 25 and this would evaluate to false, because 100 is not less than 100. since this evaluates to false, we'll exit the loop and in the simulation we will stop rolling the die.
hope this helps!
