## anonymous one year ago 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

HI!!

2. misty1212

one area is black out of four total right?

3. anonymous

right :)

4. misty1212

ratio is $$1:4$$ i.e. $$\frac{1}{4}$$

5. anonymous

so you just turned the ratio into a fraction right?

6. misty1212

yes

7. misty1212

one out of four, $$\frac{1}{4}$$

8. anonymous
