Number of students = 26
Number of students without siblings = 4
⇒ Number of students with at least one siblings = 26 - 4 = 22
Number of students with brothers = 17
Number of students with sisters = 7
⇒ Number of students with both a brother and a sister = 17 + 7 - 22 = 2
P(student has a brother, given that they have a sister) = 2/7
Answer: 2/7
I think the answer might be x=24
35 to the second power would be the same as multiplying 35 by itself so.....
Ex. 35 to the second power would be
35x35
35 to the third power would be
35x35x35
35 to the fourth power would be
35x35x35x35
And etc.
35x35=1,225
