Answer:

3/10

Step-by-step explanation:

There are totally 5 disks. On the first pick, there are 3 red discs. So

P(red disc on first pick ) = 3/5

Assuming that a red disc has been picked the first time, there will be 2 red discs and 2 blue discs so

(P red disc on second pick given red disc on first pick) = 2/4

P(red disc on both picks) = 3/5 x 2/4 = 3/10

Tatiana [17]
If you would like to know the solution to the system of equations, you can do this using the following steps:

y = –5x + 3
<span>y = 1
</span>_______________
1 =<span> –5x + 3</span> 
5x = 3 - 1
5x = 2    /5
x = 2/5 = 0.4

(x, y) = (0.4, 1)

The correct result would be (0.4, 1<span>).</span>

hammer [34]

Answers:

  • 10 people absent
  • 15 people working in the field only
  • See the below image for the venn diagram

=======================================================

Explanation:

  • 35 people are working in both places.
  • 50 work in the field or both, so 50-35 = 15 people work solely in the field.
  • 65 work in the office or both, so 65-35 = 30 people work solely in the office

So far that accounts for 15+30+35 = 80 people who work in the field, the office, or both.

The remaining 90-80 = 10 people are absent.

The venn diagram is below.
