Imagine you have m distinct baskets in which you’re throwing n number of balls at random. Each throw is independent of any other

throw, and every basket is equally as likely to get a ball on a throw. After the n throws, what is the probability that a given basket is empty?

Answer:

(\frac{m-1}{m})^n

Step-by-step explanation:

Given a basket, the probability of a ball to end there is \frac{1}{m} (because there are m baskets).

Then, the probability of a ball to end in other basket is \frac{m-1}{m}.

Finally, the probability of the basket to remain empty after n throws is

(\frac{m-1}{m})^n

This last is because, given n independets events with probability p, the probability for all of them to happen is p^n. In this case p=\frac{m-1}{m}

4 feet is 48 inches.

50/5=10

The class needs to make 10 tiles.

What equation shows 10x-2y=10 in slope intercept form
Vesna [10]
10x-2y=10 We need to solve this equation for "y" to put it into slope intercept form:

10x-2y=10
-2y = -10x +10 Subtracted 10x from both sides
y = 5x - 5 Divided both sides by -2

y = 5x - 5 Is slope intercept form

you deposit 1000 in savings account that earns .5% each month assuming you do not deposit or withdraw any money from the account
ikadub [295]

Answer:

$1015.11

Step-by-step explanation:

Compounded interest rate formula: A = P(1 + r/n)^t

Step 1: Plug in known variables

A = 1000(1 + 0.005/12)^36

Step 2: Multiply it all together

1000(1.00042)^36

1000(1.01511)

1015.11

This is a pretty bad bank considering only giving you .5% interest per month.

What is the solution to the equation 7(a – 10) = 13 – 2(2a 3)?
geniusboy [140]
7(a - 10) = 13 - 2(2a + 3)
7a - 70 = 13 - 4a - 6 = 7 - 4a
7a + 4a = 7 + 70
11a = 77
a = 77/11 = 7
a = 7.
