Jan tossed a coin 50 times and got a head 20 times. What is the experimental probability? What is the theoretical probability?

The standard answer for this is 50%.  

Step-by-step explanation:

  However, this is based on the implicit assumption that the coin is fair.

If there are reasonable grounds to doubt that the coin is fair, the theoretical probability must be based on observed statistics.   In this scenario, the probability is 60%.  

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
