I am assuming that you want verification.
Yes. If u = 10, x = 15.
x + 10 = 25
x + (10 - 10) = 25 - 10
x = 15
(88+96+98+90+x)/5=94
Add all the numbers
(372+x)/5=94
Multiply both sides by 5
372+x=470
Subtract 372 from both sides
x=98
Double check:
88+96+98+90+98=470/5=94
Hope that helps

Answer:
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.
D I’m guessing since it’s the only one that makes sense
