We can modify the RAND function to make it return a random number between any two numbers. In our example, we want to get a random number between 1 and 100.

The formula looks like:

=RAND() * (100 - 1) + 1

=RAND() * (max - min) + min

To apply the formula, we need to follow these steps:

  • Select cell B3 and click on it

Help! In a coin toss I have a 1 in 2 (fifty-fifty) chance of getting heads or tails. I need a formula to determine my chance of getting 4 heads in a row or 4 tails in a row out of 10 coin tosses. If I get 4 in a row I win. What formula can I use to determine my chances of winning if I repeat the 10 tosses for hundreds or thousands of times? I get as far as =RANDBETWEEN(0,1) but I have not been able to figure out what formula to use to determine if there are 4 in a row in a group of 10 tosses, times thousands of groups with 10 tosses in each group. Thank-you for any help you can provide.
