Answer:
a. The probability of taking out a purple flower is 0.47.
b. The probability that out of a sample of 5 flowers at least 3 flowers are yellow 0.56.
c. The standard deviation of the distribution for proportion of yellow flowers is 0.22.
d. The probability that out of the 263 samples, at most 150 of them are yellow is 0.90.
Step-by-step explanation:
D is the answer because it says each and that’s a key word to understand that it’s multiplying
2.5 km because 1.5 is half of 3 and half of 5 is 2.5
66 is the answer
76+ 38= 114
114+ 66 = 180
