It works because soap is made up of molecules with two very different ends. One end of soap molecules love water - they are hydrophilic. The other end of soap molecues hate water - they are hydrophobic. Hydrophobic ends of soap molecule all attach to the oil.

Arturiano [62]

Answer:

P(S_3|A) = \frac{2}{9}

Explanation:

Given

P(S1) = 0.3           P(S_2) = 0.5      P(S_3) = 0.2

P(A|S_1) = 0.3       P(A|S_2) = 0.1     P(A|S_3) = 0.2

Required

Determine P(S_3|A)

Using Bayes' theorem:

P(S_3|A) = \frac{P(S_3) * P(A|S_3)}{P(S_1) * P(A|S_1) + P(S_2) * P(A|S_2) + P(S_3) * P(A|S_3)}

So, we have:

P(S_3|A) = \frac{0.2 * 0.2}{0.3 * 0.3+ 0.5* 0.1 + 0.2 * 0.2}

P(S_3|A) = \frac{0.04}{0.18}

Multiply by 100/100

P(S_3|A) = \frac{4}{18}

P(S_3|A) = \frac{2}{9}
