Answer:
First question: -0.577 cannot be a probability.
Second question: The number must be between 0 and 1, inclusive (D)
Third question: -0.577 cannot be a probability.
Step-by-step explanation:
A probability is a real number that is in the interval [0, 1]. Therefore, any number outside this range cannot be considered a probability. Under this premise:
First question: -0.577 cannot be a probability.
Second question: The number must be between 0 and 1, inclusive (D)
Third question: -0.577 cannot be a probability.
Using the student id given above, a = 19 and b = 7
Average speed for the first 54 km = 48+a km/h
Plug a = 19
Average speed for the first 54 km = 48+19 = 67 km/h
Average speed for remaining 86 km = 43-b km/h where b = 7
Average speed = 36 km/h
Average speed of entire journey = total distance / total time taken
Time taken to cover 54 km = 
hr
Time take to cover 86 km = 
hr
Total time taken = 3.2 hours.
Total distance = 86+54= 140 km
Average speed of the entire trip = 
= 43.75 km/ h
