0.42 is the probability of a person having a dog or cat.
Probability is the ability to happen. The subject of this area of mathematics is the occurrence of random events. From 0 to 1 is used to express the value. To forecast how likely occurrences are to occur, probability has been introduced in mathematics. The degree to which something is likely to happen is essentially the definition of probability. This is the fundamental theory of probability, which is also applied to the probability distribution, and from which you will discover the likelihood of results for a random experiment. We must first determine the total number of outcomes in order to calculate the probability that a single event will occur.
P(dog) = 0.16,
P(cat) = 0.31, and
P(dog and cat) = 0.05, respectively.
Put the general addition rule to use.
P(dog or cat) = P(dog)+P(cat)-P(dog and cat)
and is expressed as 0.16 + 0.31 - 0.05 = 0.42.
