Please help with probablilty?

The probability of one juror voting guilty is determined to be 90%.

What is the probability that all 12 jurors will vote guilty after hearing the same evidence?

Update:

Thanks to both of you. I calculated the same answer using binomial prob. formula. Intuitively it seemed low.

    .9^12 = .2824 or about 28 and a quarter percent.

    If they all have the same probability of voting as the juror, the probability that all 12 jurors will vote guilty after hearing the same evidence is

    (0.90)^12 =0.2824
