Answer:
P = 1/6 or 0.1667
Step-by-step explanation:
Let A,B and C be the three events and 1,2 and 3 be the three dates. The sample space for this problem is:
{A1,B2,C3} {A1,B3,C2} {A2,B1,C3} {A2,B3,C1} {A3,B1,C2} {A3,B2,C1}
There are six possible outcomes and since there is only one correct answer, the possibility of guessing all 3 questions right is:
P = 1/6
P = 0.1667
Answer:
690 and 6,900
Step-by-step explanation:
230
x 33
______
690
+ 6,900
________
7590
11. 57% = 0.57
12. retail price = c + (0.57c)
13. retail price = 45 + (0.57 x 45)
retail price = 45 + 25.65
retail price = $70.65
14. 57% was added to the original price of the chain which is $25.65
