An electronic components manufacturer submits tenders to three separate companies for a work over the next month. From past experience the contracts manager estimates that the probability that each tender will be accepted as in the table below.
Company Probability
A 0.8
B 0.6
C 0.9
Calculate the probability that at least one tender is accepted:
This is my attempt:
I have assumed this is independent.
Pr(at least one tender) = Pr(A) + Pr(B) + Pr(C) + Pr(A U B) + Pr(A U C) + Pr(B U C) + Pr(A U B U C)
