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:
A 20/28
Step-by-step explanation:
Answer:
4th option
Step-by-step explanation:
She purchased a DVD for $28.
$50 - $28 = $22
1. 22 < 22
2. 22 > 22
3. 22 < 78
4. 22 > 78
I would say it would be the 4th option because she can only spend less than 78.
I can be very incorrect though, don't depend on me that much. Just make sure to think about my answer and what you would answer.
103 stays because it is the whole number and the next number after the decimal is below 5.
103 is your answer.
Answer: The missing angle is 13°
Step-by-step explanation:
Let ∠B
be the missing angle.
Let ∠A
be the angle that measures
77∘Let ∠C
the right angle that measures
90∘
The following is true of all triangles:
∠A+∠B+∠C=180∘
Express the above equation as
∠B
in terms of the other angles:
∠B=180∘−∠A−∠C
Substitute the values for ∠A and ∠C
∠B=180∘−77∘−90∘
∠B=13∘
