Answer:
The probability that one of the factory's bikes passed inspection and came off assembly line B is 0.564.
Step-by-step explanation:
Given : A bicycle factory runs two assembly lines, A and B. 97% of line A's products pass inspection and 94% of line B's products pass inspection. 40% of the factory's bikes come off assembly line B and the rest come off line A.
To find : The probability that one of the factory's bikes passed inspection and came off assembly line B ?
Solution :
The probability of line B's is P(B)= 40%=0.4
The probability of line A's is P(A)=100-40= 60%=0.6
Let E be the passes inspection.
The probability of line A's products pass inspection is P(E/A)=97%=0.97
The probability of line B's products pass inspection is P(E/B)=94%=0.94
The probability that one of the factory's bikes passed inspection and came off assembly line B is
Therefore, The probability that one of the factory's bikes passed inspection and came off assembly line B is 0.564.

basically I learned this trick at school, you take the percent, in this case it’s 95/100 and then you write it next to the fraction of what your unit is, so x/20 students
then you multiply 95 and 20 then divide by 100.
Answer:
The probability is 0.683
Step-by-step explanation:
To calculate this, we shall be needing to calculate the z-scores of both temperatures
mathematically;
z-score = (x-mean)/SD
From the question mean = 78 and SD = 5
For 73
z-score = (73-78)/5 = -5/5 = -1
For 83
z-score = (83-78)/5 = 5/5 = 1
So the probability we want to calculate is within the following range of z-scores;
P(-1 <z <1 )
Mathematically, this is same as ;
P(z<1) - P(z<-1)
Using the normal distribution table;
P(-1<z<1) = 0.68269 which is approximately 0.683
