I believe the answer is D :)
The probability that it doesn't land on 4 would be 3/8. This is because theres a 5/8 chance it lands on 4 so just do the opposite which would be 3/8.
If all the angle formed by line segments QA and AB has the same degree as the angle formed by line segments AB and BP, and line the following sets of line segments have the same length, then they are congruent triangles.
AP and QB
AQ and BP
Hope this helped.
For number 3, it is reciprocal
and for number 4, it is whole number
