A number cube with faces labeled from 1 to 6 was rolled 20 times. Each time the number
kari74 [83]

Answer:

0.4

Step-by-step explanation:

These are the relative frequencies of each face (data are missing in the text of the problem):

Number Showing  on Top Face   Frequency

1 0

2 3

3 3

4 6

5 3

6 5

The probability to obtain a certain number when throwing the dice is given by

p(x_i)=\frac{f_i}{\sum f}

where

f_i is the relative frequency of the number x_i to occur

\sum f is the sum of the relative frequencies

Here the sum of the frequencies is:

\sum f=0+3+3+6+3+5=20

For number 5 here, we have:

f_5 = 3 (from the table)

So the probability of getting a 5 is

p(5)=\frac{3}{20}

For number 6 here, we have

f_6=5

So the probability of getting a 6 is

p(6)=\frac{5}{20}

So the probability to obtain either a 5 or a 6 in the next rolling is:

p(5\cup 6)=p(5)+p(6)=\frac{3}{20}+\frac{5}{20}=\frac{8}{20}=0.4

maxonik [38]

Answer:

We cannot know.

Step-by-step explanation:

It only mentions that Phineas has more jolly ranchers than Alan. Since Alan has 10 jolly ranchers, the number of jolly ranchers Phineas could have is 11, 12, 13, 14... and so on. Phineas could have 1 billion jolly ranchers.
