This question, please!!!

Answer:

14.28%

Step-by-step explanation:

I'm not sure if it's right but this is how I worked it out,

the box's contents are 4.2 pounds in total,

therefore in a fraction it would be 6/42

you turn a fraction into a percentage you do the numerator divided by the denominator

6÷42=0.142857(decimal form)

now you just turn it into a percentage

14.28%

please correct me if I'm wrong

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
