Expert's answer

Let’s saythat P(A) = 0.4 – probability of visiting the Art InstituteP(M )=0.3 – probability of visiting the museumof science and industry

P(A and M)probability of visiting both of them

P(A or M)- probability of visiting the art institute or museum ofscience and industry

We’ll use aformula: P(A or M)=P(A)+P(M)-P(A and M)

Let’s put givenvalues into formula: P(A or M)=0.4+0.3-0.1=0.6
