Answer:

0.2 = 20%

Step-by-step explanation:

The combinations that yield a total of 6 or lower include:

(1,1), (1,2), (1,3), (1,4), (1,5),

(2,1), (2,2), (2,3), (2,4),

(3,1), (3,2), (3,3),

(4,1), (4,2),

(5,1)

(15 combinations in total)

The combinations resulting in a total of 4 are:

(1,3), (2,2), (3,1)

(3 combinations in total)

Thus, the probability of obtaining a sum of 4, given that the total is 6 or less is:

P = 3/15 = 0.2 = 20%

Answer:

together they rake leaves in one minute.

Step-by-step explanation:

If Maya takes x minutes to rake, then in one minute, she rakes leaves.

For Carla, if her raking takes y minutes, in one minute she rakes leaves.

Thus, to find the amount they work together in one minute, we add both of their contributions for that minute, resulting in:

Finally, simplifying this expression gives:

As a result, they collectively rake leaves in a minute.

Add 3b to both sides, then simplify. Next, divide both sides by 6 and simplify it further, leading to the result of a = 4b/3.
