It is a binomial distribution probability problem.
- number of trials n = 6;
- number of success trials k >= 3;
- Probability of success on a single trial p = 0.70.
We need calculate P(n=6; k>=3; p=0.7).
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=6; k>=3; p=0.7) = 0.92953, or 0.9295 (rounded). ANSWER
