Explanation / Answer

Ans:

P(oppose)=0.56

P(strongly oppose/oppose)=0.7

a)P(oppose and strongly oppose)=P(oppose)*P(strongly oppose/oppose)=0.56*0.7=0.392

b)P(does not strongly oppose/oppose)=1-0.7=0.3

P(oppose and does not strongly oppose)=0.3*0.56=0.168

c)As,P(oppose and strongly oppose)=0.392>0.05

So,This is not unusual as probability is not less than or equal to 0.05.

Option A is correct.
