Ur answer would be B.. Hope it helps let me know if its right or not!
Answer:The claim is correct
Explanation:Assume the given triangle ABCperimeter of triangle ABC = AB + BC + CA ............> I
Now, we have:D is the midpoint of AB, this means that:
AD = DB = (1/2) AB ..........> 1E is the midpoint of AC, this means that:
AE = EC = (1/2) AC ...........> 2DE is the midsegment in triangle ABC, this means that:
DE = (1/2) BC ...........> 3perimeter of triangle ADE = AD + DE + EA
Substitute in this equation with the corresponding lengths in 1,2 and 3:perimeter of triangle ADE = (1/2) AB + (1/2) BC = (1/2) AC
perimeter of triangle ADE = (1/2)(AB+BC+AC) .........> IIFrom I and II, we can prove that:perimeter of triangle ADE = (1/2) perimeter of triangle ABC
Which means that:perimeter of midsegment triangle is half the perimeter of the original triangle.
Hope this helps :)

<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
