Question 1162028
<br>
I think the question that is asked is open to different interpretations.  I read the problem differently than the other tutor.<br>
In choosing the toppings to put on the hamburger, the person preparing it must answer a YES/NO question as to whether or not to include each of the 6 toppings.  That's 2 different choices for each of 6 questions, making 2^6 = 64 possible sets of answers, meaning there is a total of 64 different possible combinations of toppings.<br>
There are 6 combinations that consist of a single topping.<br>
So the probability of getting a burger with exactly 1 topping is 6/64 = 3/32.<br>
