t a constant rate.
A) It is valid because the graph shows a constant rate of change.
B) It is valid because 30 years is long enough to evaluate the increase.
C) It is not valid because the scale on the vertical axis is inappropriate.
D) It is not valid because the scale on the horizontal axis is inappropriate.

Answer:
The probability that the message will be wrong when decoded is 0.05792
Step-by-step explanation:
Consider the provided information.
To reduce the chance or error, we transmit 00000 instead of 0 and 11111 instead of 1.
We have 5 bits, message will be corrupt if at least 3 bits are incorrect for the same block.
The digit transmitted is incorrectly received with probability p = 0.2
The probability of receiving a digit correctly is q = 1 - 0.2 = 0.8
We want the probability that the message will be wrong when decoded.
This can be written as:
Hence, the probability that the message will be wrong when decoded is 0.05792
