Can some solve for me step by step with explanation on how t

Can some solve for me step by step with explanation on how to get the answer. I am very weak in statistics and have no background. Deeply appreciated. Thanks

2. Hold a penny upright on its edge under your forefinger on a hard surface, then snap t with your other forefinger so that it spins for some time before falling. Based on 30 spins, what is the probability of heads? (M&M; 4.1)

Solution

the coin only has two sides, right?

so there is a 50% chance each time you spin it that it will land heads up.

So the answer would be 15/30, or 1/2.
