Answer:
The probability that a worker was taught by method A given that he learned the skill successfully is 0.72.
Step-by-step explanation:
(1)
The information provided is:
<em>A</em> = if method A is used
<em>B</em> = if method B is used
<em>S</em> = successfully learning the skill
P (A) = 0.75
P (B) = 0.25
P (S|A) = 0.80
P (S|B) = 0.95
Compute the probability that a worker was taught by method A given that he learned the skill successfully as follows:
Thus, the probability that a worker was taught by method A given that he learned the skill successfully is 0.72.
(2)
The probability is attached below.
Dividing by a fraction is the same as multiplying by its reciprocal
