Which of these is the x-intercept of x=3?

Kitty [74]

The x-intercept is C, because x is 3, and y is understood 0, so by (x,y) it's (3,0)

You are at a family reunion and the cooler contains ten bottles of soda; four Sprite, three Dr. Pepper, and three Cherry Coke. T

Answer:

$Probability = \frac{18}{1860480}$

Step-by-step explanation:

Given

Soda = 10

Sprite = 4

Dr. Pepper = 3

Cherry Coke = 3

Required

Determine the probability of picking Dr. pepper the fourth and fifth

First, we need to sum up the number of drinks

$Total = 10 + 4 + 3 + 3$

$Total = 20$

First Selection: Dr. Pepper

$P_1= \frac{3}{20}$

Since its probability without replacement;

At this stage: Dr. Pepper = 2 and Total = 19

Second Selection: Cherry Coke

$P_2= \frac{3}{19}$

At this stage: Dr. Pepper = 2; Cherry Coke = 2 and Total = 18

Third Selection: Cherry Coke

$P_3= \frac{2}{18}$

$P_3= \frac{1}{9}$

At this stage: Dr. Pepper = 2; Cherry Coke = 1 and Total = 17

Fourth Selection: Dr. Pepper

$P_4= \frac{2}{17}$

At this stage: Dr. Pepper = 1; Cherry Coke = 1 and Total = 16

Fifth Selection: Dr. Pepper

$P_5= \frac{1}{16}$

Multiply the calculated probabilities, to give the required probability

$Probability = P_1 * P_2 * P_3 * P_4 * P_5$

$Probability = \frac{3}{20} * \frac{3}{19} * \frac{1}{9} * \frac{2}{17} * \frac{1}{16}$

$Probability = \frac{3 * 3 * 1 * 2 * 1}{20 * 19 * 18 * 17 * 16}$

$Probability = \frac{18}{1860480}$
