In this question, we're given from a survey of athletes in a high school.
00:05
77 % of them are football players, 17 % are basketball players, 6 % of them play both football and basketball.
00:15
An athlete from the high school is chosen.
00:18
Let let f denote the event the athlete is a football player.
00:21
B denote the event, the athlete is a basketball player.
00:25
So probability of event f, the person is a football player.
00:29
That will be 77 % or 0 .77 decimal.
00:34
And we have probability at event b.
00:36
The person is a basketball player.
00:38
That's 17 % or 0 .17 decimal.
00:44
And both football, n.
00:51
Now, n is times set notation is intercept or is plus set notation is union...
