(8+3)n for n=6 help me please I'm not sure how to answer this problem how do I work this problem to get answer?
Andreas93 [3]

Answer:

54 ~ see below for explanation

Step-by-step explanation:

you're going to replace n with the 6 since n= 6

so (8+3)6

then you're going to add 8+3 in the parenthesis because of PEMDAS

(9)6

you're going to multiply 6 by 9 since 9 is in parenthesis (a number in parenthesis means multiply)

then you get 54 so the answer would be 54.

What is the conditional probability that exactly four heads appear when a fair coin is flipped five times
cestrela7 [59]

Answer:

5/32

Step-by-step explanation:

If a coin if flipped five times with four heads, then it has exactly one tail. The number of way to arrange four heads and one tail are as follows:

T H H H H

H T H H H

H H T H H

H H H T H

H H H H T

Essentially, there are five way because there are five "positions" where the tail could be.

Then, you need to find the total amount of possibilities for flipping a coin five times. Every time you flip it, there are two possibilities- heads and tails. Therefore, for five flips, the total amount of possibilities is

2x2x2x2x2 = 32

You know that

probability= # of desired outcome

                   ----------------------------------  

                      # of total outcomes

So the probablity is 5/32.
