The probability is greatly increased
Finally, encourage me to say: failure is the mother of success. Every failure will increase the success rate of the next one.
(showing off math)
If the probability is 10% (easy to calculate)
Then the chance of not getting the first one is 90%.
The second is 8 1%, the third is 72.9%, the fourth is 65.6 1%, the fifth is 59.049%, and the sixth is 53. 144 1%.
The seventh head is 47.8269%, the eighth head is 43.438+0%, and the ninth head is 38.889%.
The tenth head is 34.86445438+0%, the tenth head is 3 1.35438+0059609%, and the twelfth head is 28.86438+0%.
It can be seen that the RP not obtained after the sixth mission is very problematic.
I just want to say: brush slowly, and after 5-6 tasks, it basically appears.
