The penny can land two ways. The nickel can land two ways. The dime can land two ways. The quarter can land two ways.
The total number of ways that all of them can land is (2x2x2x2)= 16 possibilities.
Only ONE result shows no heads . . . TAIL-TAIL- TAIL-TAIL. All of the other 15 possibilities include at least one HEAD. So the probability is 15/16 = 93.25% .

The probability of obtaining at least one head when tossing a penny, a nickel, a dime, and a quarter is 93.75%. This is calculated by determining that there are 15 successful outcomes with at least one head out of a total of 16 possible outcomes. Therefore, the probability is 16 15 ​ .
