a bag contains 6 white marbles and 4 black marbles. a marble is drawn without replacing the first one. what is the probability of drawing a white marble on the first draw, followed by a white marble on the second?

Answers

Answer:

30/90 or 1/3

Step-by-step explanation:

This is because we know that 6+4=10. So we know the odds of drawing a white marble first is 6/10. And if we draw one without replacing it. This makes the second time 5/9 for white and 4/9 for black. We can then multiply 6/10 by 5/9 and get 30/90 which is equal to 1/3.

Hope this helps!

Answer:

1/3

Step-by-step explanation:

P=6/10 ×5/9=30/90=1/3

Assume that when adults with smartphones are randomly​ selected, ​44% use them in meetings or classes. If 8 adult smartphone users are randomly​ selected, find the probability that exactly 2 of them use their smartphones in meetings or classes.

Answers

Answer: The probability is 0.448

Step-by-step explanation:

First, 44% of adults use their smartphones in meetings or classes, then the probability that a random adult uses their smartphone on a meeting is:

p = 0.44

Then the probability that a random adult do not use it is:

q = 1 - 0.44 = 0.66

If 8 adult smartphone users are randomly​ selected, find the probability that exactly 2 of them use their smartphones in meetings or classes.

For a random (and fixed) case, the probability will be equal to the product of the individual probabilities for each person, this leads to:

P = (0.44)*(0.44)*(0.66)*(0.66)*(0.66)*(0.66)*(0.66)*(0.66)

P = (0.44)²*(0.66)⁶ = 0.016

And now we need to consider the different combinations. If we have C combinations, then the probability for the event will be C*P.

Remember that if we have N elements, the total number of different groups of K elements (from these N elements) is:

[tex]C(N,K) = \frac{N!}{(N - K)!*K!}[/tex]

In this case, we have N = 8, and K = 2

Then we get:

[tex]C(8, 2) = \frac{8!}{(8 - 2)!*2!} = \frac{8!}{6!*2!} = \frac{8*7}{2} = 4*7 = 28[/tex]

Then there are 28 different combinations.

This means that the probability is:

Probability = 28*P = 28*0.016 = 0.448

Probability = 0.448

Answer:

After five months, the total cost would be the same.

The 24/7 Truck Rental Company has been charging an initial rental fee of $29 plus $2.50 per hour for rental of their small trucks. After a change in pricing policy, the new fee will be $19 up front plus $3.25 per hour. After how many hours of renting the truck will the new plan be more expensive than the old plan

Answers

Answer:

14 hours

Step-by-step explanation:

Old plan :

Initial fee =. $29

Hourly fee = $2.50

New plan :

Initial fee = $19

Hourly fee = 3.25

Let number of hours = x

When new plan will be more expensive than old plan :

19 + 3.25x > 29 + 2.50x

3.25x - 2.50x > 29 - 19

0.75x > 10

x > 10 / 0.75

x > 13.3333

After 14 hours
