Question

Calculate the odds ratio (rounded off to two decimal points) for the given probability, P=0.45​

Answer 1

$\huge\green{Explain:-}$

the odds are 778 to 222 or 389 to 111. The number 389 is prime (only factors are 1 and 389), so it is not possible to simplify the odds 389 to 111 further. But if you recognize that 0.778 is 7/9 rounded to 3 decimal places, then the odds become 7/9 to 2/9 or 7 to 2.

Answer 2

the odds are 778 to 222 or 389 to 111. The number 389 is prime (only factors are 1 and 389), so it is not possible to simplify the odds 389 to 111 further.
