How many leaves on a tree diagram are needed to represent all possible combinations tossing a coin 5 time?
To represent all possible combinations of tossing a coin 5 times on a tree diagram, you would need 2^5 leaves, which equals 32 leaves. This is because each toss of a coin has 2 possible outcomes (heads or tails), and there are 5 tosses in total. Each branch on the tree diagram represents one possible outcome, leading to a total of 32 leaves to cover all possible combinations.
What is the probability of tossing two coins that are different?
The probability of tossing two coins that are different is 1 in 2, or 0.5.The probability of tossing something on the first coin is 1. The probability of not matching that on the second coin is 0.5. Multiply 1 and 0.5 together, and you get 0.5.
