Answer:
Step-by-step explanation:
There is a long way to do this. There are 36 ways that 2 dice can be rolled.
1 5
5 1
The top die is equilly likely to roll as the bottom combination. In all you have 6*6 ways that 2 dice can fall. How many ways have exactly 1 four.
4 1
4 2
4 3
4 5
4 6
Where did 4 4 go? Why wasn't it included. It wasn't included because there are 2 fours, not just one.
Is that all you can get? No. The second die would give exactly the same thing.
1 4
2 4
3 4
5 4
6 4
That's 10 ways altogether. The total number of ways of throwing 2 dice and accepting anything is 36.
The probability of throwing a 4 on one of them is 10/36 = 5/18 = 0.2777778
First make 4 1/2 improper
4 1/2 = 9/2
Divide = multiply reciprocal
9/2 * 5/3 = 45/6
Simplify 45/6
Final answer: 7 1/2
The percent of change from 12 to 15 is 25%
Answer:
x=0
Step-by-step explanation:
The total amount of people who ordered a large is 5 + 12 + 8 = 25 people.
The amount of customers who bought a large cold drink is 5.
The probability that someone bought a large cold drink is 5 out of 25 people.
This is 5/25 which is 1/5 which is .2
Convert the decimal to a fraction by multiplying by 100 and adding a percent sign at the end.
.2 x 100 = 20%
Edit:
The probability was supposed to be if the customer ordered a cold drink based on people who ordered large.
The amount of people who ordered a large drink is 22 + 5 = 27.
The amount of people who ordered a cold large is 5.
To find the percent, divide the people who ordered cold large by the total people who ordered large.
This would be 5/27 which in decimal form is .185185
To convert to a percent, multiply by 100 and add a percent sign after it.
.185185 x 100 = 18.5185%
The question says to round to the nearest percent so your answer is:
19%
