Answer:

a ) See Annex

b) P₁ = 0,0464 or P₁ = 4,64 %

c) P₄ = 0,92 or P₄ = 92 %

Step-by-step explanation:

b) P₁ [ X being defective ] = P₂ + P₃

Where P₂ is the probability of X rays machine detects a weld defective and the weld is really defective

And P₃ is the probability of X rays machine detects a weld defective and the weld is not defective

Then

P₂ = 0,04 * 0,92 = 0,0368

P₃ = 0,96 * 0,01 = 0,0096

Then P₁ = 0,0368 + 0,0096

P₁ = 0,0464 or P₁ = 4,64 %

c) P₄ = 0,04 *0,92

P₄ = 0,92 or P₄ = 92 %
