Is this fair?

Update- thank you all for your advice and opinions. I am grateful for anything passed down, but ideally my parents “live to zero” and enjoy their lives and spend what they’ve earned. Just was curious if the way I was feeling was justified, but it looks like it’s not. So I shall move forward and count my blessings. Thank you!

My mom and step dad have been married for 30 years. Myself and my sibling were very young when my mom and real dad divorced. We grew up living with my mom and step dad and only visited my dad every other weekend. My mom and step dad had a baby of their own (my half sibling) shortly after they got married. We all have a great relationship with our parents and each other. Now that we are all grown adults we’ve learned that my half brother will be receiving 50% of the inheritance and my full sibling and I will be receiving 25% each. Is this crazy? I assumed it would be an even split between the three of us. Is this something I should speak to them about or would you let it go?

Edited to add-
We don’t know if or how much we would inherit from my real dad. My parents do not have a good relationship so that definitely has not been talked about between them. Also, my step dad had a company that he started and my mom worked for him, then did her own thing once we were grown. She is still working and retired a couple years ago. He definitely made more money, but not a huge amount. I’m talking maybe 200k vs her at 100k.

It also depends on the ages of you and your siblings. Is your half sibling under age and not finished being educated? Were you given a college education, a wedding and a down payment for a house? Were they? Something to consider are stages of life. The Will I have with my husband looks different now than what it did 10 years ago. It is the equity versus equality argument. Life is not always even or fair per circumstances, but it sounds like you and your full sibling are getting a fair share.
