Found a great explanation + 1105p = £11.05
Answer:D
Step-by-step explanation:
This is combination.
If 4 books selected out of eight book in the shelf:
(4 combination 8)= 70
For hardback selection:
Then selection of 4 books out of the hardback, it means there is no paperbach will be:
(4 combination 6)= 15
So , if at least one paperback selected will be : 70-15
That is 55
Answer:

In this question, we are asked to calculate the probability of selecting a sunflower greater than a particular height.
What to do in this case is to first find the z-score based on this information given.
Mathematically,
Z-score = x- mean/standard deviation
Here, z-score will have a value of;
(16.4-14.2)/2.15 = 1.023
Therefore,
P(height >16.4ft) = P(Zscore >1.023) = 1-Fz(1.023) = 0.153
5,340,000 = 5.34 x 10^6
Hope This Helps You!
