    In a certain communications system, there is an average of 1 transmission error per 10 seconds.Assume that the distribution of transmission errors is Poisson. The probability of 2 error in a period ofone-half minute is approximately?

    X~Po(1) for 10 seconds
    So X~Po(3) for 30 seconds

    I'm sure you can work out the rest as P(X=2) is P (X<=2)-P(X<=1)

    So there's 1 error every 10 seconds
    In half a minute there's 30 seconds.
    If there are 2 errors in 30 seconds, you can use my above working in conjunction with a Poisson table of values with lambda of 3 in order to work out the answer
    kindly give me the correct answer

    That's not the way this forum works. See this thread: https://www.thestudentroom.co.uk/sho....php?t=4066671


    What do you know about the Poisson distribution?

    basically, i know little about it but this particular problem i have been defeated
    i would like to see the actual calculations please so that i can be able to follow the steps and get the concept well
