It is a binomial distribution probability problem.
- number of trials n = 10;
- number of success trials k < 2;
- Probability of success on a single trial p = 0.15.
We need calculate P(n=10; k<2; p=0.15).
To facilitate calculations, I use an appropriate online (free of charge) calculator at this web-site

It provides nice instructions and a convenient input and output for all relevant options/cases.
P(n=10; k < 2; p=0.15) = 0.54429982377, or 0.5443 (rounded). ANSWER
