Reproductive strategies

1.Semelparity

2.Iteroparity

Semelparity - When organisms reproduce only once during their life

Ex- insects, other invertebrates, and occurs in organisms such as salmon, bamboo grasses, and agave plants

Iteroparity - When organisms reproduce multiple times during their life.

It is common in most vertebrates and perennial plants, such as trees

A distribution is called a discrete probability distribution, where the set of outcomes are discrete in nature.

For example, if a dice is rolled, then all the possible outcomes are discrete and give a mass of outcomes. It is also known as the probability mass function.
