In this problem, we have been given a pie chart which gives the percent distribution of a certain country's population, estimated population for 2025.
00:11
Now, we need to find certain probabilities.
00:14
Now, the first probability is the probability of randomly selecting someone who is under five years old.
00:21
Now, from the pie chart, we can see that under five years is 4 .1%.
00:26
So that means that the required probability is 4 .5.
00:31
Now, the second question, once the probability are randomly selecting someone who is 45 years or older.
00:39
Now we can see that for 45 to 64 years we have 28 .3 percent.
00:46
And for 65 to 74 years we have 11 .9 percent.
00:51
So we add it to this.
00:53
And for 75 years or over, we have 8 .6 percent.
00:58
So if we add all of these percent, then we add all of these percent, then we will.
01:01
We get the probability of selecting someone who is 45 years or older.
01:06
So we have 28 .3 plus 11 .9 plus 8 .6.
01:13
And the value of that is 48 .8.
01:17
So the required probability is 48 .8%...
