The number of nails of a given length is normally distributed with a mean length of 5 in. and a standard deviation of 0.03 in. in a bag containing 120 nails, how many nails are between 4.97 in. long and 5.03 in. long? about 41 nails about 82 nails about 60 nails about 57 nails

z=(4.97-5)/.03=-1

z=(5.03-5)/.03=+1

area under normal curve between -1 and 1 is .683

120*.683=82.0 nails are between 4.97 in. long and 5.03 in. long.

step-by-step explanation:

a cube has 6 sides

the probability of getting 5 on the first cube is 1/6 since only one side of the cube has 5 on it.

there are 3 sides of the cube with even number on it [2,4,6]

therefore the probability of getting even number is 3/6

for both events to happen together, the probability would be

1/6 x 3/6 = 12/36

which simplifies to 1/12
