Use each digits 2,3,7,8 to make numbers FROM 20,21,22 SO ON ALL THE WAY TO 50 FOR EXAMPLE 2+3+7+8=20

Ahat [919]

2+3+7+8=20

2 x 3+7+ 8= 21

2 x 7 + 3+ 8= 25

8 x 2 + 7 + 3= 26

3 x 7 +8 - 2= 27

8 x 3 + 7 - 2= 29

8 x 7 ÷ 2 + 3= 31

7 x 2 x 3 -8 = 34

There is a couple, but i am not doing all of them
I hope this helps anyway :).

Using a fair coin and a number cube with faces numbered 1 through 6, what is the probability of getting heads and rolling a 5?

torisob [31]

Step-by-step explanation:

Use Multiplication Principle with states that if a event can occur n ways, and another mutually exclusive event occur p ways, then the total outcome is

$n \times p$

The possible ways of rolling a dice is 6 and the possible ways of flipping a coin is 2 so we have

$6 \times 2 = 12$

Now, we use the fact that proabliblity is

Number of favorable outcomes/ Total outcomes.

We can only get a head and a 5 once out of the set so the number of favorable outcomes is 1. Total outcomes is 12 so we have

$\frac{1}{12}$

A is the answer.
