No it would have to be -50 to be a negative number.
For a reflection over the x-axis, we have to change the sign of the y-value. In this case, from 13 to -13. So the reflection is (-6,-13).
Multiples of 5 are A{5,10}
multiples of 2 are B{2,4,6,8,10,12,14}
Multiples of 2 OR 5 are {2,4,5,6,8,10,12,14} for 8 possible outcomes.
Therefore the probability of spinning a multiple of 2 or 5
P(2x or 5x)=8/14 = 4/7
