If you toss 9 fair coins, in how many ways can you obtain at least one tail?

1 answer:

3 0

9/18 or 50% if you toss the coin because when you toss 1 coin you get a 1/2 chance of getting tails. Do that nine times and you get 9/18

We can convert grams to kilograms by dividing by 1000.
3500÷1000=3.5kg

Now we subtract this from her original weight
65.5-3.5= 62kg

9.3 and $9\frac{1}{4}$ were closest to another.

Explanation

First we will convert each given fractions into decimal form. So....

$9\frac{1}{2}= 9+\frac{1}{2} = 9+0.50 =9.50\\ \\ 9\frac{4}{5}= 9+ \frac{4}{5}= 9+0.80=9.80\\ \\ 9\frac{1}{4}= 9+\frac{1}{4} =9+0.25= 9.25$

Then the scores are: 9.30, 9.50, 9.80, 9.95 and 9.25

So, 9.30 and 9.25 are closest to another as their difference is (9.30-9.25)=0.05

That means , 9.3 and $9\frac{1}{4}$ were closest to another.
