Question
Suppose that you bought a package of 5 generic batteries for a new shower radio you received as a gift. However, unknown to you, one of the five batteries is defective (will not transfer any current) and the other four are good. You choose two of the five batteries at random to use in your new radio. Write the sample space for this problem,Find the probability of the following events: one battery is good and one is defective, the first battery is good or the second battery is good or they are both good,
Explanation / Answer
Assuming Battery no. 1 is defective
P(G and B) = 4/10 =0.4
P( First or Second or both ) = 6/10 = 0.6
Five Batteries : ( 1,2,3,4,5) Sample Space:( 1,2),(1,3),(1,4),(1,5),(2,3),(2,4),(2,5),(3,4),(3,5),(4,5)Related Questions
