1. A woman has 4 children. The eldest is 3 years older than the second child, who is 3 years older than the youngest child. The youngest child is one half the age of the oldest child. How old are the children.
\n" ); document.write( "---------
\n" ); document.write( "Let the youngest child be age \"x\".
\n" ); document.write( "Then oldest is age \"2x\".
\n" ); document.write( "The second child is \"2x-3\"
\n" ); document.write( "EQUATION:
\n" ); document.write( "2nd is 3 years older than youngest
\n" ); document.write( "2x-3=x+3
\n" ); document.write( "x=6 (age of youngest)
\n" ); document.write( "2x=12 (oldest)
\n" ); document.write( "2x-3=9 (second oldest child)
\n" ); document.write( "=====================
\n" ); document.write( "2. A card is cut from a pack of playing cards. Determine the probability that it will be an ace or the king of hearts.
\n" ); document.write( "Prob(ace or king of hearts)= Prob(ace)+Prob(king of hears)=4/52+1/52=5/52
\n" ); document.write( "================
\n" ); document.write( "3. A coin is tossed and a die is rolled. What is the probability of getting:
\n" ); document.write( "· A tail and a 5?
\n" ); document.write( "Prob(tail) * Prob(five) = (1/2) * (1/6) = 1/12
\n" ); document.write( "· A head and an even number?
\n" ); document.write( "Prob(head) * Prob(even number) = (1/2) * (3/6) = 1/4
\n" ); document.write( "==========
\n" ); document.write( "Cheers,
