Abicycle 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. find the probability that one of the factory's bikes passedpassed inspection and came off assembly line b.

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.

answer: howdy

step-by-step explanation:

2.2°  

step-by-step explanation:

let θ = the angle of elevation.

tanθ =77/2020

tanθ = 0.038 12

      θ = tan⁻¹0.038 12

      θ = 2.2°
