An enzyme experiment has been performed many times with the following probabilities calculate/noted: Probability experiment was successful = 0.70 Probability the right amount of enzyme was used given that the experiment was successful = 0.45 Probability the right amount of enzyme was used given the experiment was NOT successful = 0.20

Solution

IN THE EXPERIMENT ONLY TWO THINGS CAN HAPPEN EITHER RIGHT TYPE OF ENZYME WAS USED OR WRONG TYPE OF ENZYME.

WE HAVE TO CALCULATE THE PROBABILITY OF USING RIGHT YPE OF ENZYME.

PROBABILITY THAT RIGHT ENZYME IS USED AND THE EXPERIMENT IS SUCCESS = 0.45

PROBABILITY THE RIGHT TYPE OF ENZYME WAS USED AND EXPERIMENT WAS NOT SUCCESS = 0.20

HENCE THE PROBABILITY THAT RIGHT ENZYME WAS USED = 0.45+0.20 = 0.65
