Answer:
1 / 36
Step-by-step explanation:
A roll of 2 fair dice :
Total number of possible outcomes = n² ; n = number of faces in a dice = 6² = 36
Probability = required outcome / Total possible outcomes
Required outcome = total less than 3 = 1 (from sample space provided)
Hence,
P(total less than 3) = 1/36

Answer:
Step-by-step explanation:
Given the function f(m)=20-0.25m to represent the amount of money f(m) she has left after talking m minutes, the zero of the equation can be gotten by setting f(m) to 0
f(m)=20-0.25m
0 =20-0.25m
-20 = -0.25m
m = -20/-0.25
m = 80
Hence Trudy will have talked for 80minutes if she has no money left
