I’m on the smart phone & with no references to hand to back this up currently but there was a rule of thumb for Britsh/US tanks in NW Europe. In KO’d tanks, approximately 20% of tank crew were KIA & a further 20% WIA. That will include casualties sustained after bailing out but won’t always include minor injuries treated at unit level.
That isn’t the same as saying that you had 1 in 5 chance of dying if your tank was hit, as there were plenty of cases where most/all of the crew were killed, but equally there was a fair chance of the crew surviving.
The US and UK may also have counted their casualties differently, particularly in the more lightly wounded catergories, which IIRC weren’t necessarily recorded in British units if they were handled at the Regimental Aid Post and retained in the unit. I’m not sure how the US accounted for these. The Germans did it differently too.
I’ll see if I can find the reference later.
