Thread: Probability Question

Question :
The probability of error in the transmission of a bit over a communication channel is . What is the probability of more than three errors in transmitting a block of 1,000 bits?

It's a binomial distribution.

So P(X>3) = 1 - P(X <=3)

where P(X <= 3) = P(X=0) + P(X=1) + P(X=2) + P(X=3)

This is what i am getting

P(X>3) = -0.00015...............Please let me know if it is correct or no????

Not correct. For starters, a probability cannot be negative. Please show how you got this answer.
