Given:
The two way table.
To find:
The conditional probability of P(Drive to school | Senior).
Solution:
The conditional probability is defined as:
Using this formula, we get
...(i)
From the given two way table, we get
Drive to school and senior = 25
Senior = 25+5+5
= 35
Total = 2+25+3+13+20+2+25+5+5
= 100
Now,
Substituting these values in (i), we get
Therefore, the required conditional probability is 0.71.
Answer:
1)
angle 2WZX = angle ZYX ( Since all angles and sides of a rhombus are equal)
ZYX = 2 x 29.5
59
2)
4x - 10 =90 (since all angles of a rhombus intersect at 90°)
x=90+10/4
x=100/4
x=25
hope this helps
Answer:
7 apples+7 oranges
Step-by-step explanation:
If there must be LESS than 12 people in the tour group, then it would automatically take out the n>12 because n>12 represents n being MORE than 12, so your answer would be n<12. I hope you aren't totally confused, and good luck on the test!!! I am working on my math skills and I just did this quiz, so the answer is in fact, <. Make me brainliest please, would truly help.
