Here, we can use 1-(1-1/8)^5.

The probability of accidents once during the next five years has been asked and not the probability of exceeding at least once in the next 5 years.

So, 5C1(1/8)(7/8)^4 = 0.3664.

Yes, right, agree @Navi.

@Shashikanth.

Your point is right, there is a difference in once and at least once probability.
