Probability using binomial distribution

I am trying to le-learn probability theory and I am solving the following problem:

A probability that a manufactured device has $$3\%$$ or more deffects is $$p=0.02$$. If a company buys $$5$$ devices, what is the probability that at least one has $$3\%$$ or more defects.

I am thinking using binomial distribution to find probabilities that 1, 2, 3, 4 or all 5 devices are defective. So $$P(A)= {5\choose 1}p(1-p)^4+{5\choose 2}p^2(1-p)^3+{5\choose 3}p^3(1-p)^2+{5\choose 4}p^4(1-p)+{5\choose 5}p^5$$

Is this a correct approach or there is an easier way to solve the problem?

$$P(X\geq 1)=1-P(X=0)=1-{5\choose 0}\cdot p^0\cdot (1-p)^5=1-(1-p)^5$$
