Angelo chooses a number from 1 to 10. What is the probability that he chooses an odd number or a multiple of 5?

wel

Okay, so the possible numbers he can choose are :

1, 2, 3, 4, 5, 6, 7, 8, 9, 10

Pick out all the odd numbers and multiples of 5.

1, 3, 5, 7, 9, 10

Count how many numbers are odd and are a multiple of 5.

6 numbers are odd or are a multiple of 5.

So, out of 10 numbers, 6 are odd or are a multiple of 5,

Therefore, our answer is 6/10

If you would like it simplified, it would be 3/5

Or, as a decimal, it would be 60%

~Hope I helped!~

Find the missing term.

igor_vitrenko [27]

Equations are used to relate equal expressions.

The missing term is: $\mathbf{ m -1}$

The equation is given as:

$\mathbf{\frac{m - n}{m^2 - n^2} + \frac{?}{(m -1)(m -n)} = \frac{2m}{m^2 - n^2}}$

Express $\mathbf{m^2 - n^2\ as\ (m - n)(m + n)}$

So, we have:

$\mathbf{\frac{m - n}{(m - n)(m + n)} + \frac{?}{(m -1)(m -n)} = \frac{2m}{(m - n)(m + n)}}$

Multiply through by $\mathbf{m - n}$

$\mathbf{\frac{m - n}{m + n} + \frac{?}{m -1} = \frac{2m}{m + n}}$

Collect like terms

$\mathbf{ \frac{?}{m -1} = \frac{2m}{m + n} - \frac{m - n}{m + n}}$

Take LCM

$\mathbf{ \frac{?}{m -1} = \frac{2m - m + n}{m + n} }$

$\mathbf{ \frac{?}{m -1} = \frac{m + n}{m + n} }$

Divide $\mathbf{ \frac{m + n}{m + n} }$

$\mathbf{ \frac{?}{m -1} = 1}$

Cross multiply

$\mathbf{ ? =(m -1)\times 1}$

$\mathbf{ ? =m -1}$

Hence, the missing term is: $\mathbf{ m -1}$
