I think the way you should look at it is chance of failure rather than success

Say you want to roll a 6, chance of failure is 5/6 or close to 83%.

If you roll 7 times (for the 7 targes) to get a 6, your chances at not rolling a 6 = (5/6)*(5/6)*(5/6)*(5/6)*(5/6)*(5/6)*(5/6) = 27%

So using those percentages, the chance of not hitting one of the 7 targets and missing out on everything is 27%. Therefore the chance of hitting 1 target is 73%

Happy to be correct but I'm very certain we hit gas/oil in at least 1 target. Keep in mind I'm not including Baobab. Finding a commercially viable deposit however is a different aspect and would be much lower.
