Event A: The sum is greater than 5.There are 10 sums equal to 5 or less. Therefore there are 26 sums greater than 5.P = 26/36 Event B: The sum is divisible by 4.The sums that are divisible by 4 are the<span> three</span> 4's, five 8's, and the <span>one </span>12.That means there are nine sums divisible by 4. P = 9/36
If you're trying to find the missing side of the "triangle" (the distance from the house to where the ladder touches the ground), you would use the pythagorean theorem, a²+b²=c². (c is always hypotenuse)
