Answer:
To measure EBC colour, the light absorption is detected at 430 nm (MEBAK 2.16. 2 respectively EBC 9.4). ... Then the absorption will be measured in a 10mm cuvette. The sample will be diluted until the absorption is less than 2 Extinction units (E430). EBC colour = E430 x 25 x dilution factor.

Answer:
P(W|B) = 0.58
Step-by-step explanation:
The conditional probability formula tells you ...
P(W | B) = P(W&B) / P(B)
= 0.29/.050
= 0.58
