Answer:
P’ = (4, 5)
Q’ = (5, 3)
R’ = (1, 1)
Step-by-step explanation:
4 yellow + 6 green + 10 purple = 20 total tiles
1st draw P purple: 10 purple/20 total
2nd draw P purple: 9 purple/19 total
Probability purple then purple (no returns):

= 90/380
= 45/190
= 9/38
1/3 of the large circle, assuming like 1/3 like pizza cut
then cut into 1/2 of that, assuming again like pizza cut
1/2 of what it was=1/2 of 1/3=1/6 of original
original=whole circle
1/6 of whole circle=1/6 of 360=360/6=60
answer is 60 degrees
