what is the probability that at least two of the coins will be tails?

The answer is

Step-by-step explanation:

We have that  the total number of the sample for flipping the 3 coins are 6 (3!).

As it is possible to see, two events of this sample match with the possibility of having at least two of the coins being tails, therefore is the probability to have this result. After reducing the equation the answer is  .

b) k’(6, 4); l’(3, 3)

step-by-step explanation:

a 270° clockwise rotation maps every point (x, y) to (y, -x). (it negates the x-coordinate and then switches it and the y-coordinate.)

this means the endpoints of the side congruent to kl, k' and l', would be mapped as:

k'(-4, 6)→(6, 4)

l'(-3, 3)→(3, 3)

you could deduce the conclusion directly using the facts pertaining to the specific situation.

hope this .
