Answer:P (SIQ) = 0.71

Step-by-step explanation:

We know that:

P (Q) = 0.45

(∩) i guess represents the intersection of probabilities, P (A ∩B) = 0.32

then P (SIQ) is the probability of S if we know that Q already happend.

This is:

P (S) = P (A ∩B) / P (Q)

P (S) = (0.32) / (0.45) = 0.71

Then P (SIQ) = 0.71
