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.

Answer:
Well, for one thing I can't read the image--it's too small!
But I know these problems well. If I am correct, this is a spinner probability problem.
Your spinner appears to have 5 sectors, all equal in area, therefore making their probability equal.
So each of those has a prob of 1/5 in the scheme of things.
To find the combonational probability below, multiply the prob of each outcome together to find each.
Have a great day, and feel free to comment with questions!

Answer:
39 inches.
858 inches²
Step-by-step explanation:
Length:- (if length = x)
2 ( 11 + x ) = 100
22 + 2x = 100
2x = 100 - 22
2x = 78
x = 78 ÷ 2
x = 39 inches
Area:-
Area = l × b
= 39 × 22
= 858 inches²
