3. # of desired outcomes # of total possible outcomes REMEMBER... SO...
Niki has a 4/9 chance of drawing a green and
Tom has a 3/8 chance of drawing a blue.

4. # of desired outcomes # of total possible outcomes REMEMBER... SO...
Niki has a 4/9 chance of drawing a green and
Tom has a 3/8 chance of drawing a blue.

5. 4/9 x 3/8 =
12/72 or 1/6
There is a 1/6 chance that Niki will draw a green marble AND Tom will draw a blue marble End of Activity
