The required probability of the coin landing tails up at least two times is 15/16.
Given that,
A fair coin is flipped seven times. what is the probability of the coin landing tails up at least two times is to be determined.
<h3>What is probability?</h3>
Probability can be defined as the ratio of favorable outcomes to the total number of events.
Here,
In the given question,
let's approach inverse operation,
The probability of all tails = 1 / 2^7 because there is only one way to flip these coins and get no heads.
The probability of getting 1 head = 7 /2^7
Adding both the probability = 8 / 2^7
Probability of the coin landing tails up at least two times = 1 - 8/2^7
= 1 - 8 / 128
= 120 / 128
= 15 / 16
Thus, the required probability of the coin landing tails up at least two times is 15/16.

Answer:
At least one of the integer must be equal to zero to obtain the product zero
Step-by-step explanation:
we know that
When multiplying integers
, if one or both of the integers is 0, then the product is 0.
The multiplication property states that the product of any number and zero is zero.
so
a*(0)=0
therefore
At least one of the integer must be equal to zero to obtain the product zero
therefore

Answer:
72 = x
Step-by-step explanation
154 is one of the degrees for that angle. And I seen 82 for the other one.
All you have to do is subtract 154 and 82 and you get 72.
