Answer:
The chance of losing five games in a row is 0.8 × 0.8 × 0.8 × 0.8 × 0.8 = 0.85 = 0.328. The chances of that not happening is 0.672. That’s the chance that you will win at least one game out of the five. 67.2%.
Much later:
I just noticed that this question had details that are now in a comment:
I already know the technique: 1 - (0.8)^5
But I wanted to know how to do it in other ways
Sadly Quora no longer shows the question details below the question the way it used to. My answer explained it in the way the asker indicated in their comment that they already knew and they wanted something different. Sorry about that. At this point, I’m not inclined to try figuring out other ways (enumerating all the sequences, for example, and tallying the probabilities).
Step-by-step explanation:
Answer:
C
Step-by-step explanation:
just plug in 3 to x and solve
2 π r = (substitute the circumference you are given)
Then rearrange to find r on its own
So it would be
r = circumference given / 2 π
OK, here we go. Golf Club first
You subtract the total amount they need to raise, by the amount they already have:
2620 - 1225 = $1395.00 to go
Divide that number by the price of golf balls to find out how many more they need:
1395/25 = 55.8
This means that they need to sell at least 56 golf balls to meet the target.
Now to the Percussion Club...
Do the same thing again:
2400 - 1314 = $1086 to go
1086/18.25 = 59.51
So the percussion club needs to sell at lest 60 more tubs of popcorn to reach their target.
Hope this helps!! :)
Answer:
Your answer would be C: 4
Step-by-step explanation:
Well, I mean, 4 is greater than 3, but is less than 5. Which proves the n > 5 part wrong.
