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=
b) both will need repair?
Probability both will need repair =
c)at least one car will need repair
Neither car will need repair=
Probability that at least one car will need repair= 1-0.49 = 0.51
A right circular cone has a circle as its base.
All answers that have B = l * w cannot be correct as that is the area of a rectangle, not a circle.
The area of a circle is A = pi r^2, so you need B = pi r^2 in the formula.
The only formula that is correct is choice D. V = 1/3 Bh, where B = pi r^2
