Hi,
Well, I have a test tomorrow and I was hoping that's someone could maybe help me?
I don't understand probability...
Here's a question I don't understand:
Find the probability of tossing three coins and getting only two tails.
Can anyone help?
it's called the Theoretical Probability... Can anyone help???
never mind, I found out myself =]
Did you get 3/8 ?
Of course, I'd be happy to help you understand probability!
To find the probability of tossing three coins and getting only two tails, we need to consider the total number of possible outcomes and the number of successful outcomes.
Let's break it down step by step:
1. Find the total number of outcomes when three coins are tossed. For each coin, there are two possibilities (heads or tails). Since there are three coins, the total number of outcomes is 2 * 2 * 2 = 8.
2. Determine the number of successful outcomes. We want to find the probability of getting exactly two tails. One way to do this is by using combinations. We have three coins, and we need to choose two of them to be tails. The number of ways to do this is given by the formula "n choose k," where n is the total number of coins (3) and k is the number of tails we want to have (2). The formula for "n choose k" is n! / (k! * (n-k)!), where "!" denotes factorials. Plugging in the values, we get 3! / (2! * (3-2)!) = 3.
3. Calculate the probability by dividing the number of successful outcomes by the total number of outcomes. In this case, the probability is 3/8.
So, the probability of tossing three coins and getting only two tails is 3/8.
I hope this explanation helps you understand probability better. If you have any more questions, feel free to ask!
