Respuesta :

I think the answer is 0.7 you add the probabilities up to 12. 

From the histogram, we have to calculate P(4<X≤12)

In order to calculate thi, we will break this down to two probabilties

P (4<X[tex] \leq [/tex]8)

and

P (8<X[tex] \leq [/tex]12)

The probability P (4<X[tex] \leq [/tex]8) refers to the second bar on the histogram

The probability P (8<X[tex] \leq [/tex]12) refers to the third bar on the histogram

We add the two probabilities to get the final answer

P (4<X[tex] \leq [/tex]8) = 0.1

P (8<X[tex] \leq [/tex]12) = 0.35

Therefore, P(4<X≤12) = 0.1 + 0.35 = 0.45

P(4<X≤12) = 0.45
