Choose a random number between 1 and 20. What is
the probability that the
number is greater than 5
and less than 15
Oh

There is 20 numbers total. Between 5 and 15, there is 10 numbers. But to be greater than 5 you’d count 6, 7, 8, 9, 10, 11, 12, 13, and 14 to still be less than 15. This means there is 9 numbers out of 20 that could fit within your numerical range. This is written as 9/20, 0.45 or 45%

If it’s greater than 5 and less than 15 with those numbers included then it would be 5, 6, 7, 8, 9, 10, 11, 12, 13, 14 and 15. This would be written as 11/20, 0.55 or 55%

I hope this helps.

The answer is a good luck
