Answer:

$\dfrac{4}{15} \approx \bold{0.267}$

Step-by-step explanation:

Given that:

Number of lemon - lime flavored bottles = 8

Number of orange flavored bottles = 7

Bottles are picked one by one.

First for the friend and then for the person himself.

To find:

The probability that both the bottles drawn are of lemon-lime flavor.

Solution:

Total number of bottles available in the cooler = 8 + 7 = 15

Formula for probability of an event E can be observed as:

$P(E) = \dfrac{\text{Number of favorable cases}}{\text {Total number of cases}}$

$P(First\ lemon-lime) = \dfrac{8}{15}$

Now, lemon - lime flavored bottles left = 7

Total number of bottles left = 14

$P(Second\ lemon-lime)=\dfrac{7}{14}$

Required probability:

$P(Both\ lemon - lime) = \dfrac{8}{15}\times \dfrac{7}{14}\\\Rightarrow P(Both\ lemon - lime) = \dfrac{4}{15} \approx \bold{0.267}$

The mean score when the outlier removed is 8.

<u>Step-by-step explanation:</u>

The number of quiz scores were 15.

The scores are 3,6,7,7,7,7,8,8,8,8,8,9,9,10,10.

That is he scored 4 times 7, 5 times 8, 2 times 9 and 10.

The mean $m=\frac{sum of all the values}{total number of the values}$ .

Here $m=\frac{3+6+7+7+7+7+8+8+8+8+8+9+9+10+10}{15}$ .

$m=\frac{115}{15}$ .

m= 7.67.

If outlier 3 is removed then remaining score are 6,7,7,7,7,8,8,8,8,8,9,9,10,10.

The number of quiz scores will be 14

The mean $m=\frac{sum of all the values}{total number of the values}$ .

Here $m=\frac{6+7+7+7+7+8+8+8+8+8+9+9+10+10}{14}$ .

$m=\frac{112}{14}$ .

m= 8.

The mean score when the outlier removed is 8.
