luck

I drew the short straw.

She chalked her success up to luck.

She thought of her success as the result of luck.

She is blessed with good sons.

As it happens, I do know him.

We're lucky.

No matter what I do, I have bad luck.

I'm lucky, so I'll be fine.

I won a camera in a lottery.

She was lucky to have passed the exam.

She envies my good fortune.

I was fortunate enough to succeed.
