Answer:
4/6 or 2/3. Depends if your teacher wants it reduced.
Step-by-step explanation:
Each number has a 1 out of 6 chance to be rolled. so it's 1/6 for rolling a 3, 1/6 for rolling a 4, 1/6 for rolling a 5, and 1/6 for rolling a 6. 4 x 1/6 = 4/6
T2-t1=6, t3-t2=-3, t3=-6
t3-t2=-3 becomes
-6-t2=-3
-t2=3
t2=-3
t2-t1=6 becomes
-3-t1=6
-t1=9
t1=-9 degrees
