59. The results of an investigation by an expert on a fire accident are summarisedbelow:(i) Probability (there could have been a short circuit) = 0.8.(ii) Probability (LPG explosion cylinder) = 0.2.(iii) Chance of fire accident is 30% given a short circuit and 95% given an LPG explosion.Based on these, what do you think is the most probable cause of fire?Bast.
