<PRE><B>Question 346629</B>
Suppose that 7% of the bolts produced by a machine are defective. If 10 bolts are chosen from a huge shipment and inspected, determine the probability that
----
Binomial Problem with n=10 and p = 0.07
----- 
a. exactly one bolt is defective
P(x=1) = 10C1(0.07)*(0.93)^9 = binompdf(10,0.07,1) = 0.3643
----------------------------------------------------------------
b. at least two bolts are defective
Ans: 1-binomcdf(10,0.07,1) = 0.1517
-----------------------------------------
c. at most one bolt is defective
Ans: binomcdf(10,0.07,1) = 0.8483
-----------------------------------------
d. at least one bolt is defective.
Ans: 1-binomcdf(10,0.07,0) = 0.5160
