Answer:
0.03
Explanation:
For the purpose of the question we will employ the formulas used in Poisson Distribution

Where
= Probability
= Average number of errors
= Required number of errors
From the given information we can extract the following information
Artist 1
= 3
= 0
Artist 2
= 4.2
= 0
Now since this is an OR condition, we find their individual probabilities and add them

Adding these together
