Question

Answer 1

Step-by-step explanation:

Each coin has a 1 in 2 chance of being heads. By the way it doesn't matter if you toss them together or one at a time. So 1/4 or 25% of the tosses will fail to be any tails therefore 3/4 or 75% will succeed i.e. at least 1 tail. Originally Answered: Two coins are tossed simultaneously.mark as brilliant plz
