The first question is to identify a pair of similar triangles. The answer for that would be GCB and BEP. they are not the same size but they do both identify as triangles so that is correct. The next question is explain how you know the triangles in part A are similar. Because they have the same points and when they are reflected they stay the same. Last question is find the distances fromB to E and from P to E. That’s simple. 250 feet and 225 feet. Hope this helps!
Answer:
Let X be the number of times the target is hit. The probability P(X≥1) then equals 1 minus the probability of missing the target three times:
P(X≥1) = 1− (1−P(A)) (1−P(B)) (1−P(C))
= 1−0.4*0.3*0.2
= 0.976
To find the probability P(X≥2) of hitting the target at least twice, you can consider two cases: either two people hit the target and one does not, or all people hit the target. We find:
P(X≥2)=(0.4*0.7*0.8)+(0.6*0.3*0.8)+(0.6*0.7*0.2)+(0.6*0.7*0.8) = 0.788

The answer would be 1/3 because they surveyed 9 kids, and 3 were in the middle of the Venn diagram, and 3/9 can be simplified to 1/3
