Tony, Kim Vo, Chris and Amalia's word question

question #4: Brian is trying to guess a 2-digit number. So far he knows that the tens' digit is greater than 6, and the ones' digit is odd. He also knows that many two digits are different. How many possibilities are there?
Answer: The answer is 13
Solution: we knew the tens digit was greater than 6 so we used the numbers 7, 8 and 9 foir the tens numbers. We also knew that the ones digit was odd and that you cannot have the same to digits together in one number like the number 77.
The combinations you can have are 71, 73, 75, you cant have 77 though because those two numbers are the same. You can have 79, 81, 83, 85, 87, 89, 91, 93, 95 ,97 but you cant have the number 99. There are 13 combinations in all.

Qustion 8

The question:
Jason Jolt is lending part of his art collection to the local library. He has 5 oil paintings and two water colours. The library would like to borrow two oil paintings and one watercolour. In how many different ways can Jason choose the three paintings?

The answer:
You can start by making a chart like this one below.

Oil painting #1 Oli painting #2 Oil Painting #3 Oil painting #4
op1, op2 op2, op3 op3, op4 op4, op5
op1, op3 op2, op4 op3, op5
op1, op4 op2, op5
op1, op5

Oil painting #5


(there are none in this combination because we have used them all)
____________________________________________________________________
There is a total of ten combinations if you just use oil paintings, but you must double that number because you have to multiply it by 2 since there are 2 watercolours. This will give you a total of 20 different combinations.
