In a certain game, you perform three tasks. You flip a quarter, and success would be tails. You roll a single die, and success would be a odd number. You pick a card from a full playing-card deck, and success would be picking a heart card. If exactly one of these three tasks is successful, then you win the game. What is the probability of winning?  Choose the correct answer:
A) 7/16	B) 1/16	C) 25/8	D) 11/13	E) 8/13
Event(1): Probability of getting tail in a flip of coin = 1/2   Event(2): Probability of getting odd number in a roll of dice = 3/6 = 1/2   Event(3): Probability of getting heart in a pack of card = 13/52 = 1/4   Probability of winning is having exactly one successful event is:   P(success 1)* P(Fail 2)* P(Fail 3) + P(Fail 1)* P(Success 2)* P(Fail 3) + P(Fail 1)* P(Fail 2)* P(Success 3)   = 1/2*1/2*3/4 +1/2*1/2*3/4 +1/2*1/2*1/4   =3/16 + 3/16 +1/16   =7/16   7/16nswer :7/16
