Answer:
0.625
Explanation:
The image below was not posted for the but is needed to anser the question.
Further Explanation:
Mohamed carried out 24 trials of a simulation
Therefore, Total frequencies = 24
To get number of frequency greater than 3 we have to use the result in the result in the graph to obtain the estimate. Look at the graph below, when you count the dots that are on number of boxes purchased greater than 3, you will get 15.
Therefore, Number of frequency greater than 3 = 15
P(more than 3 boxes) = 15/24 = 0.625
Answer: 
Step-by-step explanation:
Given : Number of choices for novels = 4
Number of choices for plays = 6
Number of choices for poetry books = 5

Total books =4+6+5+5=20
If he wants to include all 4 novels, then the number of books left to select = 9-4=5
Remaining choices for books = 20-4=16
Number of combinations of n things taking r at a time : 
Then, the number of different reading schedules are possible :_

Hence, the required answer is
