Jason determined that some teens like to eat vanilla ice cream, some like to eat chocolate ice cream, and others don't like to eat chocolate or vanilla. he calculated the probabilities and created the venn diagram below: a venn diagram showing two categories, vanilla and chocolate. in the vanilla only circle is 0.4, in the chocolate only circle is 0.3, in the intersection is 0.2, outside the circles is 0.1 what is the probability that a teen eats vanilla ice cream, given that he/she eats chocolate ice cream?

Hence, the probability that a teen eats vanilla ice cream, given that he/she eats chocolate ice cream is:

2/5

Step-by-step explanation:

Let A denote the event that teen eats Vanilla ice-cream.

B denote the event that teen eats Chocolate ice-cream.

and A∩B denote the event that teen eats both chocolate and vanilla ice-cream.

Now , let P be the probability of an event.

We are asked to find:

P(A|B)

We know that the probability i.e. P(A|B) is given by:

We are given:

Let x be the total number of people who are surveyed.

We have:

A=0.6 x.

B=0.5 x

A∩B=0.2 x

Hence,

and,

( Since, 0.2+0.3=0.5)

Hence,

P(A|B)=0.2/0.5

i.e.

P(A|B)=2/5

i leave the calculator work to you.

7. diameter 4 miles, circumference 4π miles

8. radius 0.2 miles, circumference 0.4π miles

[this is a bad problem because the actual radius of a car on the track is less than 0.2 miles so the answer is less than 0.4π miles]

9. radius 6 feet, circumference 12π feet

10. diameter 14 cm, circumference 14π cm

11. diameter 4.8 feet, circumference 4.8π feet
