Len flipped a coin 3 times and got a head each time. What are the chances he will get a tail on his next toss? Explain reasoning.
would it be 50/50 because there are two sides
Yes
The chances of getting a tail on Len's next toss of the coin is still 50/50, or in other words, it is equally likely to get a head or a tail.
The reasoning behind this is based on the fact that each coin toss is an independent event. The outcome of one toss does not affect the outcome of another toss.
Regardless of the results of the previous flips, the coin still has two equally likely sides - heads and tails. The previous outcomes have no impact on the future tosses. So, no matter how many times Len has already flipped and obtained heads, the probability of getting heads or tails on the next toss remains the same: 50% for each outcome.
