The outcome A="At least one" means {1,2,3,4,5......n} where n is the maximum possible outcome.
The only other outcome (B) left (i.e. the complement of the above event "at least one") is (B)={0}.
Therefore, by Kolmogorov's second axiom, A and B are complements, and
P(A)+P(B)=1
therefore
P(A)=1-P(B), or in words,
Probability of outcomes of "at least one" is the complement of the outcome of "0" item.
Answer:
60% decrease
Step-by-step explanation:
you would do 5-2=3 ,
5/3
and then multiply by 100
F^-1(x)= (x+7)/2
it's the inverse so adding is subtracting and multiplication is divison
