meg flipped a penny 3 times. what is the probability the results were 3 tails.
P of tail = .5
P of all 3 tails = multiply probability of individual events
.5 * .5 * .5 = ?

To find the probability of getting 3 tails when flipping a penny 3 times, we need to determine the total number of possible outcomes and the number of favorable outcomes.
Let's start by determining the total number of possible outcomes. When flipping a penny once, there are two possible outcomes: heads or tails. Since we are flipping the penny 3 times, the total number of possible outcomes is 2 × 2 × 2 = 8.
Now let's determine the number of favorable outcomes. We want to get 3 tails, so there is only one favorable outcome: tails, tails, tails (TTT).
Therefore, the probability of getting 3 tails when flipping a penny 3 times is 1 out of 8, or written as a fraction, 1/8. This can also be written as a decimal, 0.125, or as a percentage, 12.5%.
So, the probability is 1/8 or 0.125 or 12.5%.
