Answer:
96
Step-by-step explanation:
First we can express in numbers how many students are freshman :
(28:100)=0.28 (percent into integer)
Then we multiply this number with 1600
1600*0.28=448 (this is the number of freshman)
Now we do it again with the number of juniors
(22:100)=0.22
1600*0.22= 352
Now we only subtraction these two numbers
448-352= 96
So we now know that there is 96 more freshmens than juniors
Answer: Probability that she attended class regularly given that she receives A grade is 0.9286.
Step-by-step explanation:
Since we have given that
Probability of those who attend regularly receive A's in the class = 35%
Probability of those who do not regularly receive A's in the class = 5%
Probability of students who attend class regularly = 65%
We need to find the probability that she attended class regularly given that she receives an A grade.
Let E be the event of students who attend regularly.
P(E) = 0.65
And P(E') = 1-0.65 = 0.35
Let A be the event who attend receive A in the class.
So, P(A|E) = 0.35
P(A|E') = 0.05
So, According to question, we have given that
Hence, Probability that she attended class regularly given that she receives A grade is 0.9286.
Multiple the numerator and denominator by 5.
15/20=75/100
75/100=0.75
