Statistics - Probability and Sample Space

Question

1) The probability of an automatic window button working on a five year old ford car is 0.984. A student owns a five year old ford car with four automatic window buttons. What is the probability that at least one of her automatic window buttons is not working?

 

2) Suppose we roll one fair 6-sides die with one hand and flip a fake 2-sided coin with the other hand. Find the complete sample space 

Answer 1

1) the probability of at least one of the window buttons not working = 1-probability they all work

 

= 1-(.984)⁴

 

= 1-.9378

 

= .062

 

2) does the fake coin have the same thing on both sides?
