Let E be the event that a corn crop has an infestation of ear worms, and let B be the event that a corn crop has an infestation of corn borers. Suppose that $P ( E ) = 0.23 , P ( B ) = 0.11$, and $P ( E$ and $B ) = 0.05$. Find the probability that a corn crop has no corn borer infestation.
A) $0.77$
B) $0.89$
C) $0.66$
D) $0.29$

The probability that a corn crop has no corn borer infestation is the complement of the probability that it has a corn borer infestation, which is $1 - P(B) = 1 - 0.11 = 0.89$.

Let E Be the Event That a Corn Crop Has P(E)=0.23,P(B)=0.11P ( E ) = 0.23 , P ( B ) = 0.11P(E)=0.23,P(B)=0.11

Let E Be the Event That a Corn Crop Has $P ( E ) = 0.23 , P ( B ) = 0.11$
