Apizza shop offers nine toppings. no topping is used more than once. what is the probability that the toppings on a pizza are pepperoni, onions, and mushrooms?
i think the way to solve it is 9c3 which equals 84. and the probability would be 0.012. but my friend is telling me its wrong because he did it by multiplying 1/9 x 1/8 x 1/7.
can someone tell me who is right?

start with a line segment pq that we will copy. mark a point r that will be one endpoint of the new line segment. set the compasses' point on the point p of the line segment to be copied. adjust the compasses' width to the point q. the compasses' width is now equal to the length of the line segment pq.

no he doesnt because "-16' is negatiive
