Step-by-step explanation:
It is given that The probability a person is infected by a certain cold virus is 0.2 that is p=0.2, then q=1-0.2=0.8.
Now, we have to find the probability that at least one person will be affected by the cold virus, that is P(x>1).
P(x>1)=1-(P(x=0)+P(x=1))
=
=
=
=
=
=
=
=
Thus, probability that at least one person will be affected by the cold virus will be=0.726.
