The probability of choosing one correct number is 44/3939.

The prob. of choosing 2 s 44/3939 * 43/3938.

And so on...

In product notation it looks like this:

\prod_{n=0}^{43} \frac{44-n}{3939-n} \approx 2.149332 \cdot10^{-104}.

If you're wondering why i'm subtracting it's because each time you choose a number the # of choices decreases.

2x - 6 = 60 - x  \\ add \: x \: to \:both \: sides \\  2x + x - 6 = 60 - x + x \\ 3x - 6 = 60 \\ add \: 6 \: to \: both \: sides \\ 3x - 6 + 6 = 60 + 6 \\ 3x = 66 \\ divide \: both \: sides \: by \: 3 \\  \frac{3x}{3}  =  \frac{66}{3}  \\ x = 22

Express 85mm as a percentage of 1metre​
vampirchik [111]

Answer:

Step-by-step explanation:

85/1000 because we said that 1 meter = 1000 mililiters

Divide both sides by 5 and then you have 17/200

then divide both sides by 2 (to get it over 100) =

8.5/100

.085%

Hope that helps!!

You could also just do 85/1000 you would get the same answer!!
