Answer 1

Answer:

  P(blue shirt | large shirt) = P(blue shirt)

Step-by-step explanation:

1st choice

P(B | L) = P(B&L)/P(L) = (35/77) = 5/11

P(B) = 75/165 = 5/11

So, we have P(B | L) = P(B) is true.

__

2nd choice

P(L | R) = P(L&R)/P(R) = 42/90 = 7/15

P(R) = 90/165 = 6/11 ≠ 7/15

Then P(L | R) ≠ P(R) and the choice is false.
