Does it make sense to own AAPL when I also own BRK-B and VOO?

I’m still getting my head around this so I need some insight

Say hypothetically, I own 10 shares of VOO and BRK-B. I also own 20 shares of AAPL.

VOO and BRK-B both have big AAPL share so does it make sense to own AAPL shares on its own when 2 ticker owns a lot on their own portfolio?

Thanks.
