5. (5 points) Consider a binary code with 5 bits (0 or 1) in each code word. Two examples of code words are 001010I and 101100. In each code word, a bit is a zero with probability 0.3, independent of any other bit. 1) {2 points) How many different code words are there? 2) If 3 points) \"That is the probability that a code word contains exactly three ones
