The manufacturer

The manufacturer found that 3% of the plates produced had a malfunction. Of the complaint, 75% are first and 25% second. What is the probability of producing first and second-class plates?

Correct answer:

p1 =  72.75 %
p2 =  24.25 %

Step-by-step explanation:

q=13/100=10097=0.97 k1=75%=10075=0.75 k2=25%=10025=0.25  p1=100 q k1=100 0.97 0.75=72.75%
p2=100 q k2=100 0.97 0.25=24.25%
