1) the ones digit stays at 2 the tens increase by 1.
Probability is (outcome wanted)/(total possible outcomes). Total possible outcome is the whole area of the rectangle. Which is (18)(12)=216. The outcome wanted is just the area of the triangle. (0.5)(2)(5)=5. Now 5/216=0.02
UQ’s place = 3/4(n+1) so its 3/4 of 16 which is 12 so its the 12th place so its 24
