Answer:

Step-by-step explanation:

Ok, lets list the important things

  • only green and white slices
  • all slices same size
  • spinner A has 4/5 white slices and 1/5 green slices
  • spinner B has 3/12 white slices and 9/12 green slices

The 4 options are:

  • spinner B lands on a green slice
  • spinner A lands on a white or green slice
  • spinner A lands on a white slice
  • spinner B lands on a yellow slice

We already know that choice 2 is 100% probable and option 4 is 0% probability, because in option 2, the spinner A ONLY has white or green slices so the spinner must land on the slice. In option 4, no matter which spinner is spun no yellow slices are available to land on.

the chance of option 1 happening is 9/12 which is 3/4 which is 75%

the chance of option 3 of happening 4/5 which is 80%

option 1 has a 75% chance

option 2 has a 100% chance

option 3 has an 80% chance

option 4 has a 0% chance

this means that the order is:

1. option 4

2. option 3

3. option 1

4. option 2

because it is least likely to most likely.

hope this helped you out and if you need any questions feel free to ask

good luck in maths!
