Respuesta :

The correct answer is 7/12.

What is probability?

  • Probability is a measure of the likelihood of an event to occur. Many events cannot be predicted with total certainty.
  • We can predict only the chance of an event to occur i.e. how likely they are to happen, using it.

Let A = Getting multiple of  on the first one

     B = A total of  for both roll

P (A U B) = P(A) + P(B) - P(A ∩ B)

               [tex]\frac{18}{36} + \frac{5}{36} - \frac{2}{36} \\\\ = \frac{21}{36} \\[/tex]

                [tex]\frac{7}{12}[/tex]
