Answer:

Step-by-step explanation:
<u>Addition Law for Probability</u>

Given:



Substitute the given values into the formula and solve for P(A ∩ B):





Centimeters = inches * 2.54
9 inches is equivalent to 9*2.54 = 22.86 centimeters
$3, $1, $5, $2, $3, $9, $1 = $24 - $1 = $23 - $1 = $22.
$22 is the estimation of the bill when all of the amounts are rounded to the nearest dollar. The estimation is greater than the total bill which is 23 cents less than the estimation. The total on the register is reasonable and accurate.
I'm pretty sure it's 7 and 1/7
