Regarding their 401k investments, the following data are obtained.
00:04
So the number that i'm going to start with is 21 because it invests in all three.
00:10
So that's 21 goes here.
00:12
Oh, and then i'm putting stocks here, bonds here, and money market here.
00:21
Okay.
00:22
So 21 goes in the middle.
00:24
Then i'm going to start with 47, 47 investments in stock funds and bond funds.
00:29
So that is the number that goes right here.
00:33
And so i have to make sure that 21 plus this number equals 47.
00:38
So 26 plus 21 equals 47.
00:42
Then for 33, stock funds in money markets, i have to make sure that 33 equals 21 plus another number, which is 12.
00:53
And then same with this one, 33 in bond funds in money markets.
00:58
So 33 minus 21 is 12.
01:02
Now for 119 invest in stock funds, i have to make sure this number plus this number plus this number plus this number equals 119.
01:11
So 60 goes here because 60 plus 26 plus 21 plus 12 equals 1119.
01:17
Then 99 for bond funds, i have to make sure that 26 plus 21 plus 12 plus this number equals 99.
01:28
Would be 40 and for the next one actually yes for the next one um 65 for money market funds so this number plus this number plus this number which is 20 equals 65 so then it says what is the probability that an employee of a company and i'm just going to change my color for this chosen at random had investments in exactly two kinds of investment funds.
02:02
So two kinds of investment funds would be these numbers here.
02:06
So i'm going to add up 26 plus 12 plus 12...
