1. 1000 bits are independently transmitted from a source to a sink. The probability of a faulty transmission of a bit is 0.0005. What is the probability that the transmission of at least two bits is not successful?

2. Let P(A) = 0.3; P(B) = 0.5 and P(A B ∩ ) = 0.2.

Determine the probabilities. P(A ∪ B), P( ∩ B) and P( ∪
).
