Question

This may prove to be somewhat tricky.) Suppose that we have 10 coins, which are weighted so thatwhen flipped theith coin shows heads with probabilityp=i/10 (i= 1, . . . ,10). You randomly pick onecoin, you flip it, and it shows heads.Withoutputting this coin back, you pick a second coin. What is theprobability that the second coin shows heads, given that the first coin showed heads?

Answer:2/10

Step-by-step explanation:Probability of getting head on i’th coin = i/10

Probability

Prof getting head on 2nd coin (EventA) = 2 / 10Probability

Prof getting head on 1st coin (EventB) = 1/10Probability A given B = Pr (A/B) =

Pr (A∩B) / Pr B;where A∩B = Pr (A & B) = Pr A X Pr B

Putting in above formula :

Pr (A/B) =

[(1/10)x(2/10)]/ 1/10= 2/10
