Amath class is playing a game with 16 questions that uses the board below. once a question is called, it is not called again. find the probability of the first two questions called.

board has math across and whiz down and numbered 1-16.

step-by-step explanation:

this can be solved first with pythagorean theorem, which tells us to square both legs of the triangle and sum it. this will be equal to the square of the hypotenuse.

the hypotenuse is the side "opposite" the 90 degree angle, which is x.

so we can write using pythagorean theorem,

simplifying:

to further simplify this radical, we need to use the property  

thus
