Answer 1

Option: C is the correct answer.

C. 27%

Explanation:

The dot plot can be reoresented in tabular form as follows:

Number of vitamins Number of days

1 2

3 1

4 2

5 1

6 3

7 1

9 1

Hence, the total number of days= 2+1+2+1+3+1+1=11

Also, the number of days in which Omur's mother took 6 vitamins= 3

( Since there are 3 dots over 6)

Hence, the estimated probability that Omur's mom take exactly 6 vitamins tomorrow is:

`=(3)/(11)* 100\\\\=27.27\%\\\\\text{which\ is\ approximately}\\\\=27\%`

Answer 2

Answer: C) 27%

Explanation:

There are 3 dots (vitamins) on six and 11 dots (vitamins) total.

The probability is
`(successes(vitamins\ on\ six))/(total\ possible\ outcomes(all\ vitamins))=(3)/(11)=\large\boxed{27\%}`
