Suppose you roll two die. find the number of elements in the event space of rolling a sum of 5. a. 3 b. 4 c. 5 d. 6

step-by-step explanation:

assume that you have 3 different side lengths.   apply the pythagorean theorem here:   square each of the two shortest sides; call them a and b, so that their squares are a² and b².   also square the longest side, calling the result c².

now, if a² + b² = c² is true, the triangle is a right triangle; otherwise it is not a right triangle.

ANSWER

B. 4

EXPLANATION

The numbers on the first die are;

{1,2,3,4,5,6}

The numbers on the second die are;

{1,2,3,4,5,6}

The events of getting a sum of 5 are

2+3

3+2

1+4

4+1

There are four events.

The correct choice is B .
