Question

recheck plz !!
A spinner is separated into 4 equal pieces, as shown below:

A spinner is shown with four colors, yellow, pink, white, and black, marked on it. The arrow points towards the black color.

Jonathan spins the spinner 10 times. What is the theoretical probability that it stops on the black sector on the last spin?

1 over 40

1 over 4

5 over 2

41 over 4

Answer 1

What is the probability it stops on the black spinner, if there's 4 sections?

Answer 2

Do any of your previous spins affect your possibility of getting black on the last spin?
If it does, you multiply all the chances together.
If it does not, your chance is the same value it was the first time.
(number of black/number of all colors combined)

Answer 3

There are 4 pieces and it is spun 10 times, there are 40 chances, and if you spin once, there is 1/4 chance, but multiply that 10, and I believe you have your answer.

Answer 4

^not quite, the number of times it has been spun doesn't affect the probability of a spin. Rolling a die 10 times doesn't change the probabilities on the next roll.

Answer 5

right?
