What is the answer to 10 - 5 2/3 I suck at fractions
Free_Kalibri [48]
4 1/3 

Okay, I know fractions are scary, but we can do this alright?

First, you see the whole number on the side? Get that first.

10- 5 = 5

now we have 5 left and a scary fraction.  Don't panic, let's do this.  We know 1 is 3/3.  1 can be anything as long as the number on top and the number at the bottom are the same then it would be one.

So 3/3 is one then we can subtract:

3/3 -2/3 .

We subtract the top number and leave the one at the bottom the same.

3-2 = 1

Then we have 1/3.

As you took one away from the 5, it becomes a 4 and you put back the left over, 1/3.

Then you answer will be :

4  1/3

Consider an urn containing 8 white balls, 7 red balls and 5 black balls.
weqwewe [10]

Answer + Step-by-step explanation:

1) The probability of getting 2 white balls is equal to:

=\frac{8}{20} \times \frac{7}{19}\\\\= 0.147368421053

2) the probability of getting 2 white balls is equal to:

=C^{2}_{5}\times (\frac{8}{20} \times \frac{7}{19}) \times (\frac{12}{18} \times \frac{11}{17} \times \frac{10}{16})\\=0.397316821465

3) The probability of getting at least 72 white balls is:

=C^{72}_{150}\times \left( \frac{8}{20} \right)^{72}  \times \left( \frac{7}{20} \right)^{78}  +C^{73}_{150}\times \left( \frac{8}{20} \right)^{73}  \times \left( \frac{7}{20} \right)^{77}  + \cdots +C^{149}_{150}\times \left( \frac{8}{20} \right)^{149}  \times \left( \frac{7}{20} \right)^{1}  +\left( \frac{8}{20} \right)^{150}

=\sum^{150}_{k=72} [C^{k}_{150}\times  \left( \frac{8}{15} \right)^{k}  \times \left( \frac{7}{15} \right)^{150-k}]

List benefits of having a checking account
VikaD [51]

Checking Account Advantages

Checking account holders have access to online and mobile banking, ATMs and the use of debit cards and checks to make purchases or withdraw funds from the account. Many employees find checking accounts useful for direct deposit of their paychecks. With direct deposit, an employer automatically transfers a payroll amount into the employees banking account, saving time and avoiding trips to the bank to cash paychecks. Most checking accounts in the United Stated are also insured by the Federal Deposit Insurance Corporation, or FDIC, for up to $250,000, which ensures an account holder that his money is safely stored at the bank.


couldn't really find a list besides knowing its a easier way to give money when you dont have any on you.
