Step 1
Given:
Probability distribution of printing errors in the paper.
The probability that the next issue of the paper will have at least 1 error is obtained as below:
\(\displaystyle{P}{\left({X}\geq{1}\right)}={1}-{P}{\left({X}{<}{1}\right)}\)
\(\displaystyle={1}-{P}{\left({X}={0}\right)}\)
\(\displaystyle={1}-{0.56}\)
\(\displaystyle={0.44}\)
Thus, the probability that the next issue of the paper will have at least 1 error is 0.44.
Step 2
Answer:
Option d. The probability that the next issue of the paper will have at least 1 error is 0.44.
