Twenty-five bakery customers were surveyed to determine if they like cake or pie. The results are shown in the Venn diagram. Cir
cle C and P overlap. Circle C contains 10, circle P contains 8, and the intersection contains 4. Number 3 is outside of the circles. Given that a randomly chosen customer likes cake, what is the probability that the customer also likes pie? Two-sevenths Two-fifths Four-sevenths Four-fifths

Answer:
Probability = 2/7
Step-by-step explanation:
AS the Venn diagram is not given in the question, the question is incomplete. I've attached the Venn diagram of this question below for a better understanding of the question and its solution.
In the Venn diagram we can see that
Costumers who like Cake = 10
Costumers who like Pie = 8
Costumers who like both = 4
So it means that
Total costumers who like Cake = 10 + 4 = 14
Total costumers who like Pie = 8 + 4 = 12
We have to find probabilty that a costumer who likes cakes also likes pie
So
Total costumers who like cake = 14
Costumers out of 14 who also like pie = 4
Probability = (No. of costumers who also like pie) / (Total costumers who like cake)
Probability = 4/14 = 2/7

we have that
Step 1
<u>Find the value of AC</u>
we know that
in the right triangle ABC
substitute the values in the formula
Step 2
<u>Find the value of BC</u>
we know that
in the right triangle ABC
Applying the Pythagorean Theorem
substitute the values
Step 3
<u>Find the value of BD</u>
we know that
in the right triangle BCD
Applying the Pythagorean Theorem
substitute the values

Answer:
Rhian did better in the Math test.
Step-by-step explanation:
Given: Rhian scored out of
in a Math test. In the English test she scored
out of
.
To find: In which test did she do better?
Solution:
We have,
Rhian scored out of
in a Math test.
Rhian scored out of
in an English test.
So, first we need to find the percentage of the marks scored.
Percentage in the Math test .
Percentage in the English test .
Clearly, the percentage in the Math test is greater than the percentage in the English test.
So, Rhian did better in the Math test.
