Answer: 0.02734375
Step-by-step explanation:
Here, the total observation r trials, n = 10
Selected outcomes, r = 5
The probability of getting a right answer, p =
Since, the probability of not getting a right answer, q = 1 - p = 1- 0.5 = 0.5
Thus, By the binomial model,
The probability that of getting r outcomes in the n observation,
Thus, The probability that the student gets 5 out of the 10 questions right,

Answer:
I totally get why you are asking , how do I solve this. there is so much implied about this
Step-by-step explanation:
1st you have to recognize that ∠ACB ( in my drawing ) has that same angle as the arc from A to B , so that's implied. next you have to recognize that the triangle formed by ACB with the 124 degree angle at C is an isosceles and therefore has identical angles at A and B so that's 180 = 124 + 2A , so A = 28° and so does B , then , b/c we know that small angle... you also have to know, that the line AC is perpendicular to AD. that they from a right angle and there for... you now know , that ∠BAD is the other part of that 90 or 90= 28 + ∠BAD so ∠BAD = 62°
I went through that kinda fast, there was several "leaps" of using logic to get to the correct answer , using things you know from prior understanding about angles , circles and geometry, you are putting all of the parts together here. :/ kinda daunting in some ways.
