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:
0.26 minutes
Step-by-step explanation:
So if you want to solve this, you need to make all the units the same first. What you first need to work on is the rate, since what it is asking is minutes given distance in feet.
We know that there are:
5280 ft in a mile
60 minutes in an hour
We then convert the rate knowing this:
In short, the car is traveling 3,828 ft every minute.
To determine how many minutes it will take for the car to travel just remember that:
Now we plug in what we know and solve what we don't know:
1 qt = 2 pt.
2 pt. = 32 fl. oz.
1 pt. = 16 fl. oz.
32 + 16 + 9= 57 oz. You make 57 fl. oz. of Lemonade. Hope I could help!.
