THe height is 12 which is B

We just need hypotenuse since we got 2 legs already and cause it said “how long”.

so put it in a^2+b^2=c^2

9^2+12^2=c^2

81+144=c^2

225=c^2

now solve for c

√225=15

SO the ladder is 15 feet long

1/4

Certain

0.0

Equally Likely

5/10

Impossible

100%

Likely

75/100

1/4 - unlikely

0.0 impossible

5/10 - equally likely

100% - certain

75/100 - likely

**Step-by-step explanation:**

For probability, 0 means impossible and 1 means every single time.

So 1/4 is possible, but unlikely.

5/10 is 0.5 which is right between, so equally likely

75/100 is possible and likely
