Computer keyboard failures are due to faulty electrical
Chapter 2, Problem 127E(choose chapter or problem)
Computer keyboard failures are due to faulty electrical connects (12%) or mechanical defects (88%). Mechanical defects are related to loose keys (27%) or improper assembly (73%). Electrical connect defects are caused by defective wires (35%), improper connections (13%), or poorly welded wires (52%).
(a) Find the probability that a failure is due to loose keys.
(b) Find the probability that a failure is due to improperly connected or poorly welded wires.

QUESTION:
Computer keyboard failures are due to faulty electrical connects (12%) or mechanical defects (88%). Mechanical defects are related to loose keys (27%) or improper assembly (73%). Electrical connect defects are caused by defective wires (35%), improper connections (13%), or poorly welded wires (52%).
(a) Find the probability that a failure is due to loose keys.
(b) Find the probability that a failure is due to improperly connected or poorly welded wires.
ANSWER:Step 1 of 4
Given,
Probability of faulty electrical connects, P(E) = 0.12
Probability of mechanical defects, P(M) = 0.88
Probability of mechanical defects due to loose keys, P(K) = 0.27
Probability of mechanical defects due to improper assembly, P(I) = 0.73
Probability of faulty electrical connections due to defective wiring, P(D) = 0.35
Probability of faulty electrical connections due to improper connections, P(C) = 0.13
Probability of faulty electrical connections due to poorly welded wires, P(W) = 0.52.
