Problem.in this answer then comment below.. i will help you..

.

Please thumbs up for this solution..thanks.

.

if we need atleast 100 rolls to make sum exceeds 376 ..this means that 99 rolls make sum less than 376 ...we use this to find probability..

And here value of n is large , so we approximate this by normal distribution
