Factories and parts

A certain electronic part is manufactured by three different vendors named V1, V2, and V3.

Half of the parts are produced by V1, 25% by V2, and the rest by V3. The probability of a part being damaged given that it was produced by V1 is 1%, while it's 2% for V2 and 3% for V3.

If a part taken at random is damaged, answer the following questions.

# Individual probabilities & conditional probabilities
P_V1 = ____
P_V2 = ____
P_V3 = ____
P_D_g_V1 = ____
P_D_g_V2 = ____
P_D_g_V3 = ____

# Probability of Damaged
P_Damaged = (P_V1 * P_D_g_V1) + (____ * ____) + (____ * ____)

# Bayes' rule for P(V1|D)
P_V1_g_D = (____ * ____) / P_Damaged
