1. Is a probability mass function on the set of all nonnegative integers. 2. The probability mass function ( pmf ) can take the form of: 3. The probability mass function equals 1 at this point and 0 elsewhere. 4. The probability mass function " f " in this formulation is: 5. The inclination can be estimated from the mass function and the colliding winds. 6. The masses of stars clusters can be measured by mass function . 7. It is equivalent to, and sometimes called, the z-transform of the probability mass function . 8. We use the probability mass function for the Poisson distribution, which tells us that 9. A "'discrete probability distribution "'is a probability distribution characterized by a probability mass function . 10. Such random variables cannot be described by a probability density or a probability mass function .
