Answer: 2/15

Step-by-step explanation: To find this compound probability, first note that there is no replacement.

The probability of drawing the first white token is 4/10 or 2/5.

The probability of drawing the second token is 3/9 or 1/3 because one white token has already been taken away. Now, multiply 2/5 by 1/3 to get the answer, which is 2/15

Write the word sentence as an inequality.
zalisa [80]

Answer: 23x > 115

Step-by-step explanation:

And for "a number" we can use a variable for it

x (it can be any variable like a or b)

The product of 23 and a number implies multiplication

23x

For "greater than" use a greater than symbol

23x>

So the word sentence as an inequality is

23x>115
