Answer 1

Step-by-step explanation:

25%

Originally Answered: If a coin is tossed twice, what is the probability of getting heads both times? Both coin tosses are independent events. The probability of the first coin toss landing on Heads is 1/2. Therefore the probability of both tosses resulting in Heads is 1/2 * 1/2, or 1/4, or 25%.
