Can somebody who knows how to do probability help answer these questions correctly thanks sm! (Also the P=probability) WILL MARK BRAINLIEST WHOEVER CAN HELP WITH THIS :DDD!

8) 1/4

9) 1/4

10) 1/8

11) 3/8

Here are the correct answers :)

P(2): 1/4

P(1): 1/4

P(4): 1/8

P(3 or 5): 3/8

Step-by-step explanation:

The areas marked 1, 2, and 3 each take up 1/4 of the box. This means that the probability that you will spin the arrow and land in any of those spaces is 1/4 each.

Areas 4 and 5 are HALF the size of areas 1, 2, and 3. This means that areas 4 and 5 are half of 1/4. Half of 1/4 is 1/8.

The word "or" means that you ADD whatever two probabilities they are asking for. In this case, you add areas 3 and 5. So, add 1/4 + 1/8 = 3/8.

(an easy way to add 1/4 to 1/8 is to change 1/4 to 2/8. Then you can add the two areas easily)

-2x + 7 = 7

subtract 7 from both sides.

-2x = 0

divide both sides by -2.

x = 0

the radius is 2 times the diameter.
