Answer:
Step-by-step explanation:
Given that a machine produces defective parts with three different probabilities depending on its state of repair.
condition Good order Wearing down Needs main Total
Prob 0.8 0.1 0.1 1
Defective 0.02 0.1 0.3
Joint prob 0.016 0.01 0.03 0.056
a) 0.016
b) total = 0.056
c) If not defective from needs maintenance
Prob for not defective = 
From machine that needs maintenance = 0.07
So reqd prob = 
I think 90• I’m sorry if it’s not right
That’s hard , I don’t even know
Scientific notation is just rewritten so that it has a single digit in front of the decimal and that this is multiplied by a power of ten that makes this decimal equal to the original number.
In this case we have 2.67 million. Well a million is equal to 10^6, because 10*10*10*10*10*10=one million.
So in scientific notation you would write:
2.67X10^6
Answer: The final answer I got is -44.9
