    about transmitted information

    Please, help me with this:
    Transmitted over a communication channel information is encoded with five characters. Probability of distortion each character by interference is 0.2. When the distortion of one character information is restored in full, the distortion of two characters - with a probability of 0.5, with the distortion of three or more characters - are not restored. Interference acting on each character independently. Find the probability that the transmitted information will be accepted or properly restored.

    What is the probability of 0 bad characters?
    What is the probability of exactly 1 bad characters?
    What is the probability of exactly 2 bad characters?
