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.

Answer:
1/4 times 3/8= 3/4
Step-by-step explanation: or 0.09375 please mark me brainlest if its wrong so sorry
You have to divide so it would be
X+2/2 = y do you see what I did so then it would be
X+y = xy =2=2xy so you have to first divide then combine like terms
Answer is choice C) 4x^2-3x+9
You list off the terms in a way where the largest exponent term comes first, then the second largest exponent is next, and so forth. Note how the last term 9 is the same as 9x^0. The term 3x is equivalent to 3x^1. So what we really have is 4x^2-3x^1+9x^0. The exponents count down: 2, 1, 0
