The equation to find P(A and B) is P(A and B)= P(A) x P(B/A). P(B/A) stands for probability of B given A. First we need to find out the P(A). The P(A) is 8/13 because you have 13 marbles total and 8 white marbles. For P(B/A), it is 5/12. This is because there are 5 red marbles and given that A happened, there would only be 12 marbles left in the bag, leaving you with a 5/12 chance of getting a red marble. Now plug it in. 8/13 x 5/12 = 40/156, which simplifies down to 10/39. Thus, B is the answer.
Answer:
If your looking at a graph, you find the slope by going to a random point, and using rise/run to go to the next point. A negative slope means the function is decreasing, and a positive slope means the function is increasing.
Answer:
The first is -4 and the second is 10
Step-by-step explanation:
Solution:
<u>Note that:</u>
- Men:Woman = 3:2
- 54 women = Total woman in a company
<u>3:2 can also be written as 3x:2x.</u>
- => Men:54 = 3x:2x
- => 54 = 2x
- => x = 27
- => Men = 3x
- => Men = 3(27) = 81
- => Total employees: 81 + 54
- => Total employees: 135
There are 135 employees in total.
