A shop repairs both audio and video components. Let A denote the event that the next component brought in for repair is an audio

component. Event B is the event that the next component is a CD player (so event B is contained in A). Suppose that P(A) = 0.6 and P(B) = 0.05. What is P(B|A)?

Answer: 0.6

Step-by-step explanation:

The probability formula to find p(B/A) is :

P(B/A) = p(A n B) / p(B)

Which means that A is contain in B and p(A n B) is p(A)

p(A n B)= p(A)=0.6 × 0.05 = 0.03

p(B)=0.05

Therefore

P(B/A) = p(A n B) / p(B)=p(A) / p(B)

P(B/A)=0.03 / 0.05

P(B/A)=0.6

Oxana [17]

Answer:

$12,000,000

Step-by-step explanation:

To find her commission, create a proportion.

\frac{40}{100}=\frac{480000}{x}

To solve use cross multiplication.

40(x) = 100(480000)

40x = 48000000

x= 12,000,000

AURORKA [14]

Answer:

(x, y ) → (x + 11, y - 11 )

Step-by-step explanation:

Consider the point U and its image U'

U (- 9, 1 ) → U' (2, - 10 )

This represents a shift of 2 - (- 9) = 2 + 9 = + 11 → in the x- direction and

- 10 - 1 = - 11 ↓ in the y- direction

This can be shown in the translation rule

(x, y ) → (x + 11, y - 11 )
