It would sure help a lot if I could take a peek at the drawings of the triangles.

<u>Answer:</u>
The probability of rolling an even number and then an odd number is
Option C is correct
<u>Solution:</u>
Given, You roll a six-sided die twice.
We have to find what is the probability of rolling an even number and then an odd number?
We know that, rolling single die two times is equivalent to two dice rolling at a time.

So, now, total possible outcomes = 6 x 6 = 36
And, number of favourable outcomes = 3 even on 1st die x 3 odd on 2nd die = 3 x 3 = 9
Then, probability = 
Hence, the probability of given condition is
and option c is correct.
Answer:
We get 
Step-by-step explanation:
We are given:

We need to find (f-g)(x) (assuming there is x in the bracket, i.e. (f - g) () should be (f-g)(x))
We would simply subtract f(x) and g(x)

So, We get 
Answer:
I believe its 30

because he studied for five minutes the first day and then added five minutes per day for 6 days so i think its 30
