Answer :
Probability that the man wins money from at least one of the sources, a lottery and a card game, is equal to 17/50.
Probability that he wins from first source = 1/100
Probability that he doesn’t wins from first source = 99/100
Probability that he wins from second source = 1/3
Probability that he doesn’t wins from second source = 2/3
Probability that the man wins money from at least one of the sources = 1-(probability that the man wins no money from any of the sources)
[tex]=1-[(\frac{99}{100} )(\frac{2}{3} )] =1-(\frac{33}{50} )=\frac{17}{50}[/tex]
So, the required probability of winning the money by the man from at least one of the sources is 17/50.
