Answer: P(B)= 15 P(A^c)
Step-by-step explanation:
Multiply the first one then the second one multiply and then do to the 2nd power
Answer:
See explanation below
Step-by-step explanation:
All the odd numbers can be written as 2n-1 where n is an integer.
The sum (S) of the first n positive odd numbers can be written as:

If we change the order to a decreasing order we would write it this way:

Let's sum up both equations, we are going to pair the first number of our first equation with the first number of our second equation, we can see that each pair sums up 2n ( let's see this: (2n-1 + 1 =2n, 2n-3 + 3 = 2n, 2n-5 + 5 = 2n...)) therefore we would get n pairs that sum up 2n.

Therefore, the sum of the first n positive odd numbers is square.
3600$
Explanation:
20% x 1500 = 300
300 x 12 = 3600

4/105 In total there are 2+4+1+8=15 The probability of taking a blue is number of blue divided by number of total, so that would be 4/15. Since, it is not replaced, we can now say that there are 1 less marbles in the bag (since we took out a blue). Now probability of getting a green marble is:2/14=1/7

It could be B
