Let's see this example:

10 brsmtp02.br.abnamro.com 10 brsmtp04.br.abnamro.com 15 naxpf001.abnamro.com 15 naxpf002.abnamro.com 15 naxpf003.abnamro.com 15 naxpf011.abnamro.com 15 naxpf012.abnamro.com 15 naxpf013.abnamro.com 30 plum03ap.abnamro.com 30 walnut001ap.abnamro.com

In this case brsmtp02.br.abnamro.com has 9 out of 10 chances of being contacted and brsmtp04.br.abnamro.com have the remaining 1 out of 10

No.

The MX records are always sorted according to their priority.

brsmtp02 will be contacted 50% of the time, with brsmtp04 taking the other 50%.

Which one will be tried for a given connection attempts depends on the response from the DNS server.
