Respuesta :

This is an or probability event. To find the probability of OR eventes, we use the formula:

[tex]P(AorB)=P(A)+P(B)_{}[/tex]

Then, we need to add the probability of Wednesday, Thursday and Friday:

[tex]0.05+0.15+0.51=0.71[/tex]

Now to convert this result in percentage, we multiply by 100:

[tex]0.71\cdot100=71[/tex]

The correct answer is 71%
