Question

Suppose the probability of event A is P(A) = 2/5. What is the probability of event Anot happening P(A')? (You can give your answer as a fraction, decimal or percent)P(A') = ?

Answer 1

Step-by-step explanation

The probability of an event A not occuring is given as;

`P(A^(\prime))=1-P(A)`

Therefore;

Since

`P(A)=(2)/(5)`

We will then have;

`\begin{gathered} P\mleft(A^(\prime)\mright)=1-(2)/(5) \\ P(A^(\prime))=(3)/(5) \end{gathered}`

Answer:

`P(A^(\prime))=(3)/(5)`
