At sanger’s auto garage, 40% of the cars brought in for service need an oil change. of the cars that need oil changes, 30% also need a tire rotation. find the probability that a car that comes into the auto garage needs both an oil change and a tire rotation. a. 0.10 b. 0.12 c. 0.70 d. 0.75

The answer to this question is B.) 0.12

If 40% of people need an oil change and 30% of that number looks like this:

0.4 × 0.3 = 0.12

34.5 cm

step-by-step explanation:

generally for a circular segment of angle, θ° and radius r

arc length

= (θ/360) x circumference

= (θ/360) x 2πr

in our case, θ = 60°, π=3.142 and r = 33 cm

substitute into above formula

arc length

= (60/360) x 2(3.142)( 33) = 34.5 cm
