Answer:6/8 pounds
Step-by-step explanation:
2 1/4 - 1 1/2
- 2 times 4 plus 1 = 9/4
- 1 times 2 plus 1 = 3/2
9/4 - 3/2
-to subtract your fraction, you need to have the same denominator in each side
- 4 times 2 = 8 (this is your denominator)
- 4 times 3 = 12 (your right numerator)
- 2 times 9 = 18 (your left numerator)
18/8 - 12/8 = 6/8

Answer: Our required probability is 0.745.
Step-by-step explanation:
Since we have given that
Probability of getting good risks people = 0.05
Probability of getting average risks people = 0.15
Probability of getting bad risks people = 0.30
Probability of getting good risk accident = 0.2
Probability of getting average risk accident = 0.5
Probability of getting bad risk accident = 0.3
So, Probability of people having accident in a year is given by

Probability of people either good or average risk given that he\she had no accident is given by

Hence, our required probability is 0.745.
