A random flip of a coin gives either a "head" or "tail", with equal probabilities. Consider an experiment where we repeatedly flip a coin until we get a head. What is the probability that the first head occurs on the flip of the coin

50%

Step-by-step explanation:

A coin has two sides, so there are two outcomes.

The outcomes are of course, heads and tails.

The chance of landing on heads is 1/2. The chance of landing on tails is also 1/2.

Theoretically, 50 percent. But technically, if you flipped it a extremely large amount of times, the extremely slight weight difference would show.

Step-by-step explanation: 1/2 = two sides of the coins, only one can be landed on per flip, and assuming equal chances.

8(-10x+3.5y-7)

8×-10x + 8×3.5y + 8×-7

-80x + 28y - 56

therefore

-80x+28y-56 is the correct answer
