Question

Given the Venn diagram above what is the probability that neither event A or B will occur

Answer 1

Conider that the probability that neither event A or B will occur ​is given by the formula,

`P(A\cup B)^c=1-P(A\cup B)`

Substitute the values,

`P(A\cup B)^c=1-(0.3+0.2+0.1)=1-0.6=0.4`

Thus, the required probability is 0.4
