A certain brand of TV has a 50% chance of being defective. Which model could be used to determine the probability that when two TVs are chosen, they will both be defective? Roll a die four times Flip a coin twice Flip a coin four times None of the above

The answer is "Flip a coin twice".

Step-by-step explanation:

The probability, that its damage would be (HH, TT, HT, TH) if two of the TVs were selected, that's why the answer is "Flip a coin twice" is the correct.

step-by-step explanation:

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w
