- How much zeros has the number $1000!$ at the end?
yes it depends on $2$ and $5$ Note that there are plenty of even numbers Also note that $25\times 4 = 100$ which gives two zeros Also note that there $125\times 8 = 1000$ gives three zeroes and $5^4 \times 2^4 = 10^4$ Each power of $5$ add one extra zero So, count the multiple of $5$ and it's power less than $1000$

- probability - 1 1000 chance of a reaction. If you do the action 1000 . . .
So for your example, it would be 1-((1–1 1000)^1000) which equals 1-(0 999^1000), which turns out to be about 0 63230457, or 63 230457% There is a lot of confusion about this topic, as intuitively, you would think that if the odds are 1 1000 playing 1000 times would guarantee a win
- Is there a shortcut for raising 2 to the power of a number (e. g.
Simple way to mentally estimate 2 to any power: $2^{10} \approx 1,000$ (actually 1,024) E g , $2^{27} = 2^{20} \times 2^7 \approx 1,000^2 \times 128 = 128’000,000$ Real answer is 134 million - not bad for a mental estimate You’ll always be a bit low because you estimate 1,024 as 1,000, but you’ll be close The higher the power, the
- Find the sum of all the multiples of 3 or 5 below 1000
First of all, stop thinking on the number $1000$ and turn your attention to the number $990$ instead If you solve the problem for $990$ you just have to add $993, 995, 996$ $999$ to it for the final answer This sum is $(a)=3983$ Count all the #s divisible by $3$: From $3$ to $990$ there are $330$ terms
