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.
Y = 5 x 3 + 8
y = 15 + 8
y = 23
His cousin paid 4 per mile. You have to find the unit rate and you find that by dividing 12 by 3 which gives you 4.
Answer: Whoa that is a lot, ok so the first one is 49 and on the second one it is 34 on the third one the answer is 20 and on the fourth one I think the answer is 51. Hope that helped you :)
