Answer:

B

Step-by-step explanation:

A function is a relation in which each y-value has a unique x-value. This means that in a function x-values should never repeat. In both A and C one x-value repeats, meaning they cannot be functions. However, in table B x-values don't repeat, only y-values which is allowed by the definition of function.

Marta has a lower probability of winning than Elena has. Which could be the outcome that Marta needs to win the game? Select thr
HACTEHA [7]

Answer:

rolling a sum of 7

rolling a sum of 6

rolling a sum that is greater than 2 but less than 5

Step-by-step explanation:

There are 6 possible combination out of 36 that will result in Martha winning the game. First roll have to be even, so its: 2, 4, 6. Second roll have to be less than 3 so its: 1, 2. The combination will be:

(2, 1)= sum 3

(2, 2)= sum 4

(4, 1)= sum 5

(4, 2)= sum 6

(6, 1)= sum 7

(6, 2)= sum 8

If you look at the sum, Marta can only win if the sum is between three and eight inclusive. If the sum is less than three or higher than eight then its impossible for Marta to win.

The third option is wrong, Marta can't win when the sum is 2 (less than three) or 9(higher than eight) since both sum is not possible.

Fourth option is wrong, highest sum Marta can get is eight.
