Daniel can paint a house in 10 days, while his father can paint the same house in 6 days. If they work together, how long will they finish the job? I need asap answer pl

3 days

Step-by-step explanation:

Let the amount of work be x.

Daniel:

10 days = x

1 day = x

Father:

6 days = x

1 day = x

Together:

1 day = x + x

        = x + x

        = x

        = x

No. of days = x ÷ x

                   = x × x

                   =

                   = 3

answer: expected value of x = 1.0

step-by-step explanation:

p(x=0) = 0.25

p(x=1) = 0.50

p(x=2) = 0.25

expected value for x = 0×0.25 + 1×0.5 + 2×0.25 = 1.0
