The problem does not say anything about how many of the marbles are yellow but if you put the first one back in the bag then it is an independent probability and each one would be the same individual probability. Since the problem doesn't say and I don't know if you have it somewhere else, I'll do it as an example.
Let's say there were 6 of the 10 marbles were yellow. So the probability of the first one is 6/10 and so is the second one 6/10. To find the total probability you multiply them together 6/10*6/10=36/100=9/25
Hope that helps. If you can tell me how many yellow there are I will show the work for the specific problem.
Answer:
Use distributive property to get rid of the parentheses.
Step-by-step explanation:
9+7(x-1)=4x+14
Use the order the operations (PEMDAS)
Parentheses
Exponents
Multiply
Divide
Add
Subtract
First you need to get rid of the parentheses by using distributive property.
9+7x-7=4x+14
Legs legnth a and b, and hypotnuse c
a^2+b^2=c^2
legs are 9 and 12
a=12
b=9
12^2+9^2=c^2
144+81=c^2
225=c^2
sqrt both sides
15=c
the legnth of the hyptonuse is 15 inches
Answer:
the probabily is 3/4 that she will not land on red
Step-by-step explanation:
there are three other colors, making red have a 3/4 chance of not being picked
X greater than or equal to 82%
- I don't know how to type that sign :)
