Step-by-step explanation:
Say we are testing 100 people
we test 100 times
80 of the 100 tests result in 5 people having the disease.

therefore, 5/80/100
.065
Answer:
-3 -1
Step-by-step explanation:
Im not completely sure but i think
So prpbility is (desired outcomes)/(total possible outcomes)
there are 11 letter so 11 total outcomes
so chosing a B or an I so find how many total
2 B nd 2 I's
2+2=4
so 4/11 is the probablity
