Celine flipped a coin 100 times. She flipped heads 56 times and tails 44 times. What is the experimental probability that the next time she flips a coin it will be heads? Write your answer as a fraction in simplest form (ex: 1/2)

White shapes and black shapes are used in a game. some of the shapes are circles. while the rest are squares. the ratio of the number of white shapes to the number of black shapes is 5: 11. the ratio of the number of white cicrles to the number of white squares is 3: 7. the ratio of the number of black circles to the number of black squres is 3: 8. work out what fraction of all the shapes are circles.
