Probability Chances Are… You can do it! Activity #4

A woman has two children. What are the odds that both are boys? Show how you would solve this in your math journal.

You could set up a tree diagram in your journal: BOY (50%) BOY ( %) GIRL ( %) BOY ( %) GIRL (50%) GIRL ( %) Fill in the spaces and mark the %.

BOY (50%) GIRL (50%) BOY (50%) GIRL (50%) To find the odds, just multiply across that path that leads to two boys. .50 X .50 = .25 or 25%

Did you solve this problem another way? Share the different ways people solved this in class and write them in your journal. End of Activity
