Explanation / Answer

Ans:

a)P(male or nursing major)=P(male)+P(nursing)-P(male and nursing)

=0.323+0.202-0.027

=0.498

b)P(female or non nursing major)=P(female)+P(non nursing)-P(female or non nursing)

=0.677+0.798-0.502

=0.973

c)P(not female or not a nursing major)=P(male or non nursing)

=P(male)+P(non nursing major)-P(male and non nursing)

=0.323+0.798-0.295

=0.826
