A Biased Coin Is Such That The Head Is 4 Times More Likely To Show Up Than The Tail.What Is The Probability Of Obtaining A Head?

4/5 = .8

To find the probability of obtaining a head, we need to calculate the relative frequency or likelihood of getting a head compared to the total number of outcomes.

In this scenario, the head is 4 times more likely to show up than the tail, which means that the probability of getting a head is 4/5, while the probability of getting a tail is 1/5.

Here's how to calculate the probability of obtaining a head:

1. Assign a value to the probability of getting a tail (T). In this case, the probability of obtaining a tail is 1/5.

2. Use the information given to determine the probability of obtaining a head (H). Since the head is 4 times more likely than the tail, we can use the equation H = 4T. Substituting the value of T, we get H = 4/5.

Therefore, the probability of obtaining a head is 4/5, or 80%.
