Five cards the ten, jack, sovereign, ruler and trick card, are very much rearranged with their face downwards. One card is then gotten up.
Five cards the ten, jack, sovereign, ruler and trick card, are very much rearranged with their face downwards. One card is then gotten up.

(I) What is the likelihood that the card is the sovereign?

(ii) If the sovereign is drawn and set to the side, what is the likelihood that the subsequent card gotten is (a) an ace? (b) a sovereign?

Arrangement:

Complete quantities of cards = 5

P(E) = (Number of ideal results/Total number of results)

(I) Numbers of sovereign = 1

P (picking a sovereign) = ⅕ = 0.2

(ii) If the sovereign is drawn and set to the side, the complete quantities of cards left is (5-4) = 4

(a) Total quantities of expert = 1

P (picking an expert) = ¼ = 0.25

(b) Total quantities of sovereign = 0

P (picking a sovereign) = 0/4 = 0
