Ajar contains a mixture of 10 black balls, 8 red balls, and 2 white balls all the same size. what is the probability of
drawing either a red, black, or white ball in one draw?

The answer is 1

Step-by-step explanation:

8/20 or 0.4- probability of red ball in one draw

2/20 or 0.1 - probability of white ball in one draw

10/20 or 0.5 - probability of black ball in one draw

0.4 + 0.5 + 0.1 = 1

Sorry I'm late just wanted to put the right answer!

the final amount you will pay is $68.04.

the tip is determined by the pre-tax amount, so we calculate the tip based on the original bill, not after we've added sales tax.

to find the tip:

we can divide 54.00 by 100 to get 1% of 54. then we multiply that by 18.

54 / 100 = .54

.54 x 18 = 9.72

tip = 9.72$

to find the tax:

we can divide 54.00 by 100 to get 1% of 54. then we can multiply that by 8 to get 8%.

54 / 100 = .54

.54 x 8 = 4.32

tax= 4.32

now we can add the tip and tax to the bill to get our total.

54 + 9.72 + 4.32 = 68.04

total: $68.04
