Answer:
P(Green ball) = 1/3
Step-by-step explanation:
You have a sack of 90 balls. 35 blue, 30 green and 25 pink. If you randomly pull one ball out of the bag, what is the probability of pulling a green ball?
The Probability of pulling a green ball =
P(Green ball) =
Number of green balls/ Total number of balls
= 30 green balls/90 balls
P(Green ball) = 1/3
In a right triangle, the hypotenuse is always the longest side. Plus, the hypotenuse squared has to equal the sum of the squares of the other 2 sides. For the first "triangle" above: does
? Let's check. 196 = 25 + 16 so does 196 = 41? Obviously not. So that is not a right triangle. Let's check the second one the same way. Does
? 25 = 9 + 16. Does 25 = 25? Of course it does! So 1 is not a right triangle, but 2 is!
