Answer:
Step-by-step explanation:
1/4 + 5/8
= (2+5)/8
= 7/8
I’m here to help what’s the problem?
As, v=√2as
Squaring both sides,
v²=2as
∴ s= v²/2a
Answer: (D) 16%
Step-by-step explanation:
Binomial probability formula :-
, where n is the sample size , p is population proportion and P(x) is the probability of getting success in x trial.
Given : The proportion of students in College are near-sighted : p= 0.28
Sample size : n= 20
Then, the the probability that in a randomly chosen group of 20 College students, exactly 4 are near-sighted is given by :_

Hence, the probability that in a randomly chosen group of 20 College students, exactly 4 are near-sighted is closest to 16%.
