PLEASE HELP <br> Which of the following are true if event A and B are independent
makkiz [27]

Answer:

a) P(B/A) = P(B)

Step-by-step explanation:

<u><em>Step(i):-</em></u>

Given that A and B are independent events

P(A∩B) =P(A) P(B)

we will use the conditional probability

              P(A/B) = \frac{P(AnB)}{P(B)}

                     or

            P(B/A) = \frac{P(AnB)}{P(A)}<u></u>

<u> Step(ii):-</u>

Given that A and B are independent events

P(A∩B) =P(A) P(B)

 P(B/A) = \frac{P(AnB)}{P(A)}<u></u>

P(B/A) = \frac{P(A)P(B)}{P(A)} = P(B)

P(B/A) = P(B)

The radius of a 10 inch right circular cylinder is measured to be 4 inches, but with a possible error of ±0.1 inch. What is the
lidiya [134]

Answer:

25.13274125 in³


Step-by-step explanation:

The radius = 4 ± 0.1

height = 10

Volume of a cylinder = πr²h

Actual volume of the cylinder = π × 4² × 10

                                                  = 502.6548246

Maximum volume = π × 4.1² × 10

                              = 528.1017251

Minimum volume = π × 3.9² × 10

                              = 477.8362426

Average error = (528.1017251 - 477.8362426)/2

                        = 50.2654825/2

                       = 25.13274125 in³

The units are inches cubed.
