Need help solving please! 

In a manufacturing process, there are two types of materials used: Aluminum and Titanium.
40% of the parts produced are made from Aluminum, and 60% are made from Titanium. The
failure rates for these materials are as follows: 5% of Aluminum parts fail during production,
while 2% of Titanium parts fail during production.
Let A represent the Aluminum parts, T represent the Titanium parts, and F represent part
failure.
(a) What is the probability that a randomly selected part will fail during production?
The requested probability is
A. P (F) B. P (F|A)
. (Type A, B, C, D, or E.)
C. P (FT)
D. P(A|F)
E. P (T|F)
The probability is computed to be
(Round the answer to four decimal places.)
(b) If a randomly selected part has NOT failed during production, what is the probability that it
is made of Aluminum?
The requested probability is
. (Type A, B, C, D, or E.)
A. P (F) B. P (FA)
C. P (FT)
D. P(A|F')
E. P (T|F')
The probability is computed to be
(Round the answer to four decimal places.)
