Step-by-step explanation:
a) P(A or B) = P(A) x P(B)
P(A) x P(B) = 0.11 x 0.83 = 0.0913
b) P(A or B) = P(A) + P(B)
0.11 + 0.83 = 0.94
Answer:
The final cost after the discount and tax is $179.76
Step-by-step explanation:
Since the discount is 30%, she only pays 70% of the price of the ticket.
Discounted price before tax:
70% of $240 = 0.7 × $240 = $168
Now think of the price $168 as a new price.
The price is $168 which is 100% of the price. Tax is 7% of the price, so you must pay 107% of the price.
107% of $168 = 1.07 × $168 = $179.76
Answer: The final cost after the discount and tax is $179.76
