Question 1169271: If mortality rate for COVID 19 disease in a cetain place is 0.10.(10%).
Find the probability that out of 10 people with this disease exactly four
will survive.

90% survival
P(4)=10C4*0.90^4^0.10^6=0.00014
the mean would be 10*0.9 or 9
the variance would be 9*0.1 or 0.9
sd is sqrt 0.9 or about 0.95, so low probability makes sense.
