Answer:
a. 1/10 or 10%
b. 1/2 or 50%
Step-by-step explanation:
Since the combination of machines 1, 2 and 3 produce 100% of the total output when added together, then the probability of choosing a bolt at random that is defective is: 5 + 2 + 3 = 10% out of 100% or 10/100, which is 1/10 or 10%.
If the bolt that is choosen at random is defective, than the probability that it came from machine 1 is 5/10 or 1/2 which is also 50%.

Answer:
Step-by-step explanation:
so I can't see the picture or what the "Shaded region " is.. but I can guess that it's the part of the 3x3 rectangle with the circle removed.. right?
if that's the case... then
3*3 = 9
9 - area of circle = shaded region
area of circle = pi *
pi * 1 cm = 3.1415
9 - 3.1415 = 5.8585
5.86
I don't see this as a choice of answers so maybe that's not what the shaded region is. any way.. hope it helps
