Answer:
Step-by-step explanation:
The customer drawing a 30% discount card then the next customer 20% discount card has a probability of 5/40 for the 30% which = 12.5% and 20% is 15/40 which = 37.5% add them together then divide by 2 for a total of 25%.
The customer drawing a 10% card has a 20/40 which = 50% then a customer drawing a 20% card is 15/40 = 37.5% add them together then divide by 2 = 43.75%
The customer drawing a 10% card has a 20/40 which is 50%. Then another customer drawing another 10% is another 50% add them together and divide by 2 = 50%
The customer drawing a 20% card has a 5/40 which is 12.5% and another customer drawing a 20% card again is 12.5%. Add together and divide by 2 = 12.5%. So your answer is the 1st three.
Answer:
I believe it would be 50
Step-by-step explanation:
If those 3 hours are included in those 12 to get there, then you'd want to subtract that to get your actual time spent driving. That would leave you with 9. Then, you'd divide that by 450 to get your answer. (This is if those 3 hours are included in that 12 hour time frame.)

Step-by-step explanation:
Each term is divisible by -3, so we can "pull out" a -3. We do this by dividing each term by -3.
Because of the distributive property, multiplying -3 by the divided expression in parenthesis results in the original expression.
