First Question:
There are 4 purple marbles, 8 orange marbles and 10 blue marbles in a bag and a penny lying on a table. what is the probability of pulling out an orange marble and flipping tails with the penny?
Solve:
Since there are 4 purple marbles, 8 Orange marbles and 10 blue marbles in a bag and a penny lying on a table.
As well as, Asking for orange marbles with a penny.
Since there are 8 Orange marbles and flipping tails then the probability is 1/8
Answer = 1/8
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Second Question:
Maria has a pink shirt, a purple shirt and a blue shirt. For jackets she has a jean jacket. if she randomly picks one shirt and one jacket, what is the probability that she picks the pink shirt and the jean jacket?
Solve:
Given that she has 1 pink, 1 purple, 1 blue shirt and 1 jean jacket.
We can make a list:
Let,
Pink = Pk
Purple = PU
Blue = BL
Jean Jacket = JJ
List :
PKJJ
PUJJ
BLJJ
Thus, there 1/3 chance of getting pink shirt with a Jean jacket.
Answer = 1/3

Third Question:
Jonah spins the spinner two times. What is the probability that the first spin is a 2 and that the second spin is a 4
Given in comment: one 1's, and two 2's, two 3's and one 4
Now we know that:
Spinner number = 1,2,2,3,3,1
Total number = 6
So, there are two 2's on the spinner we can know that probability first spin is a 2 is 2/6 and since there is one 4's on the spinner we can know that probability is 1/6
And = Multiply:
2/6 * 1/6 = 1/18
Answer = 1/18

Jonah spins the spinner two times. What is the probability that the first spin is a 2 and that the second spin is a 4
Given in comment:
only one 1's, and two 2's, two 3's and one 4
Thus,
1,2,2,3,3,4
Total number = 6
Since there are two 2's on the spinner we can know that
probability first spin is a 2 is 2/6 and since there is one 4's on the spinner we can know that probability is 1/6
And = Multiply:
2/6 * 1/6 = 1/18
Hence, probability that the first spin is a 2 and that the second spin is a 4 is 1/18
