If the probability of writing the correct answer to the question on an exam is 2/5, what are the odds against writing the correc
MAXImum [283]
<h3>Answer is  3:2</h3>

Explanation

The probability of getting the correct answer is 2/5. This means there are 2 events of getting it right out of 5 events total. Since there are 2 events of getting it right, there are 5-2 = 3 events of getting it wrong.

The odds against getting the right answer is 3:2. We list the number of ways to get it wrong first, a colon, then the number of ways of getting it right.

Can someone check this please
Ivan
Let's check the answer

Start with equation (1). Plug in (x,y) = (-10,-1)
x + 5y = -15
-10 + 5y = -15 ... replace x with -10
-10 + 5(-1) = -15 ... replace y with -1
-10 - 5 = -15
-15 = -15 ... true equation

So we've confirmed one equation so far. Let's check the other equation

--------------------

Start with equation (2). Plug in (x,y) = (-10,-1)

y = (1/5)*x + 1
y = (1/5)*(-10) + 1 ... replace x with -10
-1 = (1/5)*(-10) + 1 ... replace y with -1
-1 = -2 + 1
-1 = -1

Since both equations are true when (x,y) = (-10,-1), this confirms the answer. Nice work on getting the correct answer.

Visually we can see the two lines crossing at (-10,-1). See the attached image. Note: 1/5 = 0.2 so the second equation can be written as y = 0.2x+1
