When you select a random person, the probability that this person will go to Ches Tahoe restaurant is 75% (Hint: Review Binomial Probability Distribution).
a. You randomly select 8 people. What is the probability that exactly 3 people
from that group will go to Ches Tahoe restaurant? (You must show the
steps to get the full credit) (15 points)
b. You randomly select 50 people. Use the normal approximation to the binomial
distribution find the probability that at least 35 people will go to Ches Tahoe
restaurant (Hint: mean = np: stand dev = sqrt(npq), where p + y = ?). (No
steps necessary - just write the answer) (5 points)

a= 0.0231

Step-by-step explanation:

n=8

p=0.75

q=1 - 0.75 = 0.25

(p=x)

p(5) = 8C5 (0.25)^5 (0.75)^8-5

p(5)= 0.0231

Or 2.31%

First four answers are correct as congruent parts of congruent triangles are congruent but L Is not the opposite to M so they wouldn’t be congruent nor does NL or PQ have the same connection
