1/6 if the spinner has six sections and each section is the same size with an equal probability of being selected.
If the spinner has six sections then the probability of any one number is one out of six.
The dice has six sides and has a probability of any one number is also one out of six.
This give 36 possible outcomes. six of the them have the same number 1,1 2,2 3,3 4,4 5,5 6,6. This gives 6/36 possibilities of having the same number on the spinner and the dice.
6/ 36 = 1/6.
Having a spinner has no effect on probability that is different from a dice assuming the spinner has six sides with equal probability
