Complete the equation, and tell which property you used 11+(19+6)=(11+)+6

Properties:

1) a+ b = b+a      Commutative

2) (a + b) + c = a + (b+c)        Associative

3) a(b+c) = ab + ac            Distributive

Here we are given

11 + (19 + 6) = (11 +___) + 6

The number 19 is missing on the right.

So we have

11 + (19 + 6) = (11 +19) + 6

This looks like Property 2 above.

Hence it is associative property.

answer:   35 % is the probability of a late departure or an early arrival.

step-by-step explanation:

let l represents the late departure and e represents the early departure.

then, according to the question,

p(l) = 12 %,   p(e) = 27 % and = 4 %

and, we have to find out,

but, we know that,

which is the required equation that will use to find the probability of a late departure or an early departure.

therefore,   the probability of a late departure or an early arrival =   35 %
