I'm not sure if it's more likely. What matters is that with open source software you are able verify the source code for accidental or intentional weaknesses.

At least in principle. In practice the fact that backdoors (or at least weaknesses) have made it into standards should show that it's not particularly easy to do so.

Also, thankfully, public-key cryptography has an inherent openness so you can usually make a good judgement on the security of the crypto used, without seeing the code. See also Kerckhoff's principle:
