I don't know for sure, but I assume multishot bullets roll for procs independently of "normal" bullets. Explaining how that works in the general case would take a crash course in probability, but in short, there'd end up being a chance for one bullet, two bullets, or (for multishot >100%) three bullets to fire, followed by a chance for no bullets, one bullet, two bullets, or (for multishot >100%) three bullets to proc. To avoid all that, let's just take an example of a weapon with 10% status chance and 60% multishot and let the method speak for itself.

There are five possibilities: 1 bullet no procs, 1 bullet 1 proc, 2 bullets no proc, 2 bullets 1 proc, and 2 bullets 2 procs. One of them (no more and no less) will happen every time you shoot, so the chances for them should add up to 100%.

1 bullet no procs: (100% - 60% multishot) * (100% - 10% status chance) = 36%

1 bullet 1 proc: (100% - 60% multishot) * (10% status chance) = 4%

2 bullets no proc: (60% multishot) * (100% - 10% status chance)^2 = 48.6%

2 bullets 1 proc: (60% multishot) * 2 * [ (10% status chance) * (100% - 10% status chance) ] = 10.8%

2 bullets 2 procs: (60% multishot) * (10% status chance)^2 = 0.6%

To confirm: 36% + 4% + 48.6% + 10.8% + 0.6% = 100%. The * 2 in "2 bullets 1 proc" is because there are two ways for a total of 1 proc to happen with two bullets: the first bullet procs and the second one doesn't, or the second bullet procs and the first one doesn't.

As for what your status chance would be, just add up the probabilities of all the outcomes that result in at least one proc. In this case, 4% + 10.8% + 0.6% = 15.4%

If you have >100% multishot, remember that 100% multishot -guarantees- that you'll fire 2 bullets and any more will give you a (multishot - 100%) chance to fire a third bullet.

Hope that helps.
