The midpoint of these two points would be (3.5, 0.5)

In order to find this, you need to take the average of the two point that you have. To do that, add the numbers together and divide by 2. Start with just the x values.

(5 + 2)/2 = 3.5

Now the y values

(-3 + 4)/2 = 0.5

This gives us the ordered pair of (3.5, 0.5)

To win the game, Elena has to roll an even number first and a number less than 3 second. Her probability of winning is 6/36.

Nitella [24]

<u>Answer:</u>

Prob (Marta winning) < Prob (Elena winning) : Case 1st, 3rd & 5th
Prob (Marta winning) = Prob (Elena winning) : Case 2nd
Prob (Marta winning) > Prob (Elena winning) : Case 4th

<u>Step-by-step explanation:</u>

Elena outcomes of winning, first even no. & second no. = 3 : (2,1) , (2,2) , (4,1) , (4,2) , (6,1) , (6,2). So, Probability (Elena willing) = favourable outcomes / total outcomes = 6 / 36

Margie dice sum '7' outcomes = (2,5) , (5,2) , (3,4) , (4,3). So, Prob = 4/36
Margie dice sum '6' outcomes = (1,5) , (5,1) , (2,4) , (4,2) , (3,3). So, Prob = 6/36
Margie dice sum '2' or '9' outcomes = (1,1) , (3,6) , (6,3) , (4,5) , (5,4). Prob = 5/36
Margie dice sum '>9' outcomes = (3,6) , (6,3) , (4,5) , (5,4) , (4,6) , (6,4) , (5,5) , (5,6) , (6,5) , (6,6). Prob = 10/36
Margie dice sum '>2,<5' outcomes = (1,2) , (2,1) , (2,2) , (1,3) , (3,1) = 4/ 36
