Answer:
0.3 chance of not drawing a blue marble.
Step-by-step explanation:
This problem can be found using the theoretical probability formula.
The formula is: P (desired outcome) = <u># of desired outcomes</u>
total number of outcomes
Now all you have to do is input the numbers into the equation.
P(not drawing a blue marble) = <u>3</u>
10
3/10 is equal to 0.3 as a decimal.
9:4, so for every 9 boys there are 4 girls. 27 is 3 times 9, so multiply 4 with 3, you get 12. Count them up and BOOM, 39
