Answer 1
Answer:

Answer:

Probability (P) (k successes out of n trials) = nCk * p^k * (1-p)^(n-k), where nCk = n! / (k! * (n-k)!)

for this problem n=20, p = 1/6(probability of rolling 1 two) is approximately 0.1667

P ( of getting more that 3 two's) = 1 -P(0 two's out of 20 trials) -P(1 two out of 20 trials) -P(2 two's out of 20 trials) -P(3 two's out of 20 trials)

P ( of getting more that 3 two's) = 1 -0.026 -0.104 -0.198 -0.238 = 0.434

My answer is A

75 of what number is 51

Answers

If you would like to solve 75% of what number is 51, you can calculate this using the following steps:

75% of what number is 51
75% * x = 51
75/100 * x = 51    /*100/75
x = 51 * 100 / 75
x = 68

Result: 75% of 68 is 51.

A recipe calls for 3 cups of sugar and 9 cups of water. How many cups of water should be used with 2 cups of sugar?

Answers

First you do 9/3
9 divided by 3 is 3
This means there is 3 cups of water for every cup of sugar
Then do 2 times 3
You would need 6 cups of water to go with 2 cups of sugar
since 3cups = 9cups ... and they are asking how much water would go in 2cups of sugar .. then the answer would be ..
6cups of water

because you cross multiply.

London Heathrow airport see on average 191,200 passengers a day how many passengers is this per minute. I need to show the steps to my answer

Answers

First you have to ask, how many minutes are in a day?
There are 60 minutes in a hour, and 24 hours a day. You would multiply these two to find how many minutes are in a day.

24×60=1440 minutes in a day.

Now to find how many passages a minute, divide the total number of passangers, by the number of minutes.
191,200÷1440=132.7778

Even though the 7 is bigger than a 5, you do not round up because it doesn't count as a full person.
132 people a minute is your answer.
