The probability of multiple events happening is found by multiplying the probabilities of each event together.

So yes, 1/10 is the answer :)
The first picture would be choice answer c because the number of x's represent how many birds wings are this size. The number on the tic mark represents the size of the wing span. So you would take the number of x's times the tic mark represented under it. There are 3 birds with 3 1/8 wingspan so it wold be 3 1/8 *3. Hoped this helps for the first one!
I'm assuming that the 1/3 is an exponent.
If so, then
![2^{1/3} = \sqrt[3]{2}](https://tex.z-dn.net/?f=2%5E%7B1%2F3%7D%20%3D%20%5Csqrt%5B3%5D%7B2%7D)
Which is the cube root of 2. Raising any value to the 1/3 power is the same as taking the cube root.
Setup: 4x-6=3x+4
<span>4x=3x+10 </span>
<span>1x=10 </span>
x = 10
The digits after the decimal separator are, in order, tenths, hundreths and thousandths. So, your number is composed by:
- 1 unit
- 0 tenths
- 0 hundreths
- 2 thousandths
So, you would call this name "one and two thousandths"
