What is the likelihood, expressed as a percentage, of rolling 2 straight 2s using one 6-sided dice?
3%
5%
17%
8.5%
Explanation
The likelihood of rolling any given number on a 6-sided dice is 16.6%, to get the likelihood of that even happening twice in a row, simply multiply 16.6% by itself, to get 2.7%, rounded up to 3%
and
.
If , then evaluate
.
Explanation
If , then
can be determined from the equation
first by substituting 18 for :
then by dividing both sides by 18 to isolate the :
Now, in the other equation, substitute 4 for :
Divide both sides by 4 to isolate the :
,
the correct choice.
