Answer:
a) 0.0374 , b) 0.6500 , c) 0.3500
Step-by-step explanation:
Pr (Both consider celebrities role models) = (213/1100) x (212/1099)
= 0.0374
Pr (None consider celebrities role models) = (887/1100) x (886/1099)
= 0.6500
Pr (atleast one consider celebrities role models) = 1 - Pr (None consider role models)
1 - 0.6500 = 0.3500
