Answer:
1. There is a <u><em>1/5</em></u> chance you will get a blue one from both bags.
2. There is a <u><em>3/32</em></u> chance you will get a 1 and then a 2.
3. There is a <u><em>5/12</em></u> chance of rolling a factor of 12 and then an odd number.
Step-by-step explanation:
<u><em>Question 1</em></u>
Add all the marbles together.
3 + 2 = 5
4 + 2 = 6
Make a fraction.
blue/all
Use it on the numbers.
3/5
2/6
Multiply them together.
6/30
Simplify.
1/5
There is a <u><em>1/5</em></u> chance you will get a blue one from both bags.
<u><em>Question 2</em></u>
Add all the numbers together.
There are 8.
Make the two crucial fractions.
ones/all
twos/all
Use them.
3/8
2/8
Multiply them together.
6/64
Simplify.
3/32
There is a <u><em>3/32</em></u> chance you will get a 1 and then a 2.
<u><em>Question 3</em></u>
Find the factors of 12.
1, 2, 3, 4, 6
Make a fraction.
factors/all
Use the fraction.
5/6
Find the odd numbers.
1, 3, 5
Make a fraction.
odd/all
Use the fraction.
3/6
Multiply them together.
15/36
Simplify.
5/12
There is a <u><em>5/12</em></u> chance of rolling a factor of 12 and then an odd number.
The probability that both marbles chosen from the bag will be yellow is 3/14.
<h3>What is the probability?</h3>
Probability determines the odds that an event would happen. The probability the event occurs is 1 and the probability that the event does not occur is 0.
The probability that both marbles chosen from the bag will be yellow = (number of yellow marbles / total number of marbles) x (number of yellow marbles - 1/ total number of marbles - 1)
4/8 x 3/7 = 3/14

#SPJ1
Y = 0:
0 is neither prime nor composite.
y=1:
3 is a prime number (because only 3 and 1 divide evenly into it)
y = 2:
8 is a composite number (because multiple different numbers divide evenly into it: 1, 2, 4, and 8)
1. can't be determined cause no info given on the rate of which the population is growing.
2. can't be determined/not true because the initial population of a could be less than b.
3. can't be determined/not true because we don't have enough info to tell how fast they grow and decline.
Y=7.8com %75 679000 then multiple them wait don't think got it right
