Need Help Fixing Partitioning after Deleting Core Storage Booter and Windows
You deleted too many partitions. You deleted the booter partition used to boot Yosemite.

Normally, the command given below would be used to reclaim the missing space.

diskutil cs resizestack 84A33FDC-BA63-43B5-A43F-E4BF61D0830A 0


However, if you issue this command, I would assume you would get an error message similar to what is shown below. The error is due to the missing booter partition and is not due to the target partition being too small.

Error: -69722: You can't perform this resize unless it has a booter (target partition is probably too small)


I am not sure if you can revert the Core Storage volume. You would have had to include the output from the command disktuil cs list in order for me to determine this.

You could try entering the command given below. This attempts to change the Yosemite volume to "Mac OS Extended (Journaled)". If successfully, you should be able to view Yosemite in the Startup Manager.

diskutil cs revert 84A33FDC-BA63-43B5-A43F-E4BF61D0830A 


If unsuccessful, you will probably need to reinstall Yosemite. If successful, you can post a new question asking how to proceed.
