The probability of getting exactly zero tails is 1/8.
Step-by-step explanation:
When a fair coin is tossed three time, the set of equally likely outcomes is:
S= {HHH,HHT, HTH, THH, HTT, THT, TTH, TTT}
n(S)=8
Let A be the event that there are exactly zero tails which means there are all heads
Then
A= {HHH}
n(A)=1

The probability of getting exactly zero tails is 1/8.

An expression which combines variables, numbers and at least one operation is called binomial. Binomial consists of two terms that is separated with at least one operation. Operations may include addition, subtraction, multiplication and division.
The < is just like and equal sign just looks a little different think of it that was for the first couple steps. So you have 13-3y<-5. First do, -5+13=8. Now you have -3y<8. Then your want to do 8 divided by -3 and you get=-2.666666667 and that equals y.
-2.7=y then make that equal sign into the normal sign again. -2.7
