(Essay Question 7 Points)Suppose you roll a six-sided die two times hoping to get two numbers whose sum is even. What is the sample space? How many favorable outcomes are there?

Answers

Answer 1

Answer:
Well I don't know.
Let's think about it:

-- There are 6 possibilities for each role.
So 36 possibilities for 2 rolls.
Doesn't take us anywhere.

New direction:
-- If the first roll is odd, then you need another odd on the second one.
-- If the first roll is even, then you need another even on the second one.
This may be the key, right here !

-- The die has 3 odds and 3 evens.

-- Probability of an odd followed by another odd = (1/2) x (1/2) = 1/4
-- Probability of an even followed by another even = (1/2) x (1/2) = 1/4

I'm sure this is it. I'm a little shaky on how to combine those 2 probs.

Ah hah !
Try this:

Probability of either 1 sequence or the other one is (1/4) + (1/4) = 1/2 .

That means ... Regardless of what the first roll is, the probability of
the second roll matching it in oddness or evenness is 1/2 .

So the probability of 2 rolls that sum to an even number is 1/2 = 50% .

Is this reasonable, or sleazy ?

Luis brings 79 pencils to school after he is each of his 15 classmates an equal number of pencils he will give any leftover pencils to his teacher how many pencils will lose teachers will see and if Luis decides to take an equal share the pencils along with his classmates will his teacher receive more pencils are fewer of pencils so you're thinking

Answers

15*5=75
79-75=4
If Luis gives each of his classmates 5 pencils each, he will have 4 leftover to give to his teacher

16*4=64
79-64=15
If Luis gives himself AND each of his classmates 4 pencils each, he will have 15 leftover to give to his teacher

So... If Luis decides to take an equal share of pencils along with his classmates, his teacher will receive more pencils.
