Need help ONLY with part d of this Intro to probability and statistics homework problem. Below is the work and answers for parts a to c.

 

Given  

From table 

n(Total)=1456, n(S1,A1)=392,n(S2,A1)=649, n(S1,A2)=241, n(S2,A2)=174 , n(A1)=1041, n(A2)=415, n(S1)=633, n(S2)=823

n(Total)=1456, n(S1,A1)=392,n(S2,A1)=649, n(S1,A2)=241, n(S2,A2)=174 , n(A1)=1041, n(A2)=415, n(S1)=633, n(S2)=823. 

 

(a) 

P(A1)=n(A1)/n(Total)=1041/1456=0.7150

(b) 

P(A1|S1)=n(A1,S1)/n(S1)=392/633=0.6193

(c) 

P(A1|S2)=n(A1,S2)/n(S2)

=649/823=0.7886

gender and by whether or not they favor a gun law.
Male (S₁)
Favor (A₁)
Oppose (A₂)
Totals
392
241
633
Female (S₂)
649
174
823
Totals
1041
415
1456
Compute the following probabilities if one of these 1456
persons is selected randomly: (a) P(A₁), (b) P(A₁ S₁),
and (c) P(A₂|S₂). (d) Interpret your answers to parts (b)
and (c).
