Notice that all eight of the angles in the center of the pattern meet to form a circle. Let a° represent the measure of each pin
k central angle and b° represent the measure of each green central angle.
Which of the following equations are true? Select all that apply.
(1) 4a° = 180°
(2) 2b° = 90°
(3) 4a° + 4b° = 360°
(4) a° = 90° - b°
(5) 2(a° + b°) = 180°

Answer:
Required probability is 0.784 .
Step-by-step explanation:
We are given that in a large statistics course, 74% of the students passed the first exam, 72% of the students pass the second exam, and 58% of the students passed both exams.
Let Probability that the students passed the first exam = P(F) = 0.74
Probability that the students passed the second exam = P(S) = 0.72
Probability that the students passed both exams = = 0.58
Now, if the student passed the first exam, probability that he passed the second exam is given by the conditional probability of P(S/F) ;
As we know that conditional probability, P(A/B) =
Similarly, P(S/F) = =
{As
is same as
}
= = 0.784
Therefore, probability that he passed the second exam is 0.784 .
