Answer: 7/13</h3>
======================================================
Explanation:
We know that the marble selected is red, so we don't need to focus on the other colors.
7 red marbles are in urn B out of 2+7+4 = 13 total red marbles.
The probability the red marble came from urn B is therefore 7/13
Answer:
Formula of standard deviation = √Variance
Standard deviation = 1
Step-by-step explanation:
X-bar is the variance
Therefore, the answer would be
√X-bar
√1 = 1
!!
2-4 is -2 and -5 times -2 is 10 divided by 2 is 5 and 5 +3 is 8. and 8 times 3 is 24. PEMDAS
A = √(18+b)(18-b), -√(18+b)(18-b)
b= √(18+a)(18-a), -√(18+a)(18-a)
take the root of both sides and solve I hope this helps
