Suppose that 22 ​thank-you notes are written and 22 envelopes are addressed.​ accidentally, the notes are randomly inserted into the envelopes and mailed without checking the addresses. what is the probability that all the notes will be inserted into the correct​ envelopes?

Respuesta :

[tex] |\Omega|=22!=1,124,000,727,777,607,680,000\\
|A|=1\\\\
P(A)=\dfrac{1}{1,124,000,727,777,607,680,000} [/tex]
