Step-by-step explanation:
1. The result should by a 2 digit number.
So, I fix a two digit number first, say 60.
Then, I multiplied it by some random integer, say 4 and got 240.
Now, 240 is my dividend and 4 is my divisor.
My division problem is:
2. The result should be a 3 digit number.
So, I fix a three digit number first, say 600.
Then, I multiplied it by some random integer, say 3 and got 1800.
Now, 1800 is my dividend and 3 is my divisor.
My division problem is:

<h2>See the explanation.</h2>Step-by-step explanation:
The coin is to be flipped 2000 times.
The probability of getting a head is 0.3.
It is given that, we need to get a head in between 575 and 618 times.
If we will get 575 heads then we will get (2000 - 575) tails.
Hence, if we take that we want to get n times head, then we will get (2000 - n) times tail.
The probability of not getting a head is (1 - 0.3) = 0.7.
The probability of getting n times head is .
The required probability is ∑ , where
.
