Answer:
Probability that a car need to be repaired once = 20% = 0.20
Probability that a car need to be repaired twice = 8% = 0.08
Probability that a car need to be repaired three or more = 2% = 0.02
a) If you own two cars what is the probability that neither will need repair?
Probability that a car need to be repaired once , twice and thrice or more= 0.20+0.08+0.02=0.3
Probability that car need no repair = 1-0.3=0.7
Neither car will need repair=![0.7 \times 0.7=0.49](https://tex.z-dn.net/?f=0.7%20%5Ctimes%200.7%3D0.49)
b) both will need repair?
Probability both will need repair = ![0.3 \times 0.3=0.09](https://tex.z-dn.net/?f=0.3%20%5Ctimes%200.3%3D0.09)
c)at least one car will need repair
Neither car will need repair=![0.7 \times 0.7=0.49](https://tex.z-dn.net/?f=0.7%20%5Ctimes%200.7%3D0.49)
Probability that at least one car will need repair= 1-0.49 = 0.51
Answer:
2nd option
Step-by-step explanation:
Answer:
The expression in simplified radical form is:
√ 25 –2√3 + √27 +2√ 9 = 11 + √3
Step-by-step explanation:
Given the expression
√ 25 –2√3 + √27 +2√ 9
as
√ 25 = 5
√27 = 3√3
2√9 = 6
so the expression becomes
√ 25 –2√3 + √27 +2√ 9
= 5 - 2√3 + 3√3 + 6
= 11 + √3
Thus, the expression in simplified radical form is:
√ 25 –2√3 + √27 +2√ 9 = 11 + √3
Answer:
Below.
Step-by-step explanation:
-5/8 * 1/3 = -5/24
-5/12 * 1/2 = -5/24
-5/6 * 1/4 = -5/24.
