4 (points for an A) x 21 (As) = 84
3 (points for a B) x 24 (Bs) =72
2 (points for a C) x 15 (cs) = 30
84 + 72 + 30 = 186 (total points)
186 divided by 60 (total credits) = 3.1

Answer:
0.78814
Step-by-step explanation:
We solve using z score
z = (x-μ)/σ, where
x is the raw score = 4.0 inches
μ is the population mean = 4.4 inches
σ is the population standard deviation = 0.5 inches
z = 4.0 - 4.4/0.5
z = -0.8
Probability value from Z-Table:
P(x<4.0) = 0.21186
P(x>4.0) = 1 - P(x<4.0)
= 1 - 2.1186
= 0.78814
The probability that the rod you chose will be greater than 4.0 inches is 0.78814.
