A fair 6-sided die is rolled 8 times and the resulting sequence of 8 numbers is recorded.
How many different sequences are possible?
How many different sequences consist entirely of even numbers?
How many different sequences are possible if the first, third, and fourth numbers must be the same?

Respuesta :

Answer:

a) 1,679,616 sequences

b) 6,561 sequences

c) 46,656 sequences

Step-by-step explanation:

a) How many different sequences are possible?

For each of the 8 dice, there are 6 possible outcomes. Therefore, the total number of difference sequences is:

[tex]6^8=1,679,616\ sequences[/tex]

b) How many different sequences consist entirely of even numbers?

For each of the 8 dice, there are 3 possible even outcomes. Therefore, the total number of difference sequences is:

[tex]3^8=6,561\ sequences[/tex]

c) How many different sequences are possible if the first, third, and fourth numbers must be the same?

If the first, third and fourth numbers are fixed, there are only 5 "free" positions, while there are 6 possible outcomes for the fixed positions since they have to be the same

[tex]6*6^5 = 46,656\ sequences[/tex]

(a) The possible different sequence is [tex]6^8=1,679,616[/tex]

(b) The possible different sequence entirely of even numbers

[tex]3^8=6,561[/tex]

(c)The possible different sequence, if the first, third, and fourth numbers must be the same [tex]6 \cdot 6^5=46,656[/tex]

Possible outcome

Possible outcome of a 6-sided die  when it is rolled 'n' times is [tex]6^n[/tex]

Given information

A fair 6-sided die is rolled 8 times and the resulting sequence of 8 numbers is recorded.

(a) 6- sided dice is rolled 8 times

The possible different sequence is [tex]6^8=1,679,616[/tex]

(b) The sequence consist entirely of even numbers

There are 3 even numbers in 6-sided dice. Even numbers are 2,4,6

There are 3 possible even outcomes.

The possible different sequence entirely of even numbers

[tex]3^8=6,561[/tex]

(c) the first, third, and fourth numbers must be the same

When the first , third and fourth numbers are fixed  then there is only one  possibility.  For the remaining free positions there are 6 possible outcomes .

The possible different sequence, if the first, third, and fourth numbers must be the same [tex]6 \cdot 6^5=46,656[/tex]
