Hello students.
00:01
We have adriana is shooting two free throws during a basketball.
00:06
And she makes 80 percentage of her free throws.
00:10
And these throws are independent events.
00:13
And we have to find a person chance that a, she is in the groove and makes both free throws.
00:20
B, makes the first and miss the second.
00:24
C, misses the first and make the second.
00:26
D struggles and misses both of her three throws and in the last one we have to find the sum of four answers.
00:36
So here we have p is equal to 80 % that means 0 .80.
00:44
Okay.
00:46
Now we can start with the question name.
00:49
She makes both the throws.
00:52
So she makes both throws.
00:55
So that is equal to we can write 0 .8 multiplied by 0 .8 equal to 0 .64.
01:12
In personage it will be 64 percentage.
01:18
Answer to the part a, she makes both rows a probability 64 percentage.
01:24
In part b, she makes the first one and she makes the first one and misses the second one.
01:29
That is probability of makes first, makes first and misses second.
01:41
Okay.
01:42
So that's we can write.
01:45
We have the probability for making 0 .80.
01:49
So missing, it will be 1 minus 0 .80.
01:52
So we can write 0 .6.
01:57
Sorry, 0 .8...
