first qn
4/36=1/9
total no. of ways to roll a dice=36
no. of ways to produce 7=3
(1+6=7, 2+5=7, 3+4=7)
no. of ways to produce 11=1
(5+6=11)
there are 4 ways in total. 4/36 simplify it to be 1/9
second qn im not sure but i think its
1/9 x 50 = 50/9 = 5 x (5/9)
round it off to the smaller whole no. which is 5 so i think its 5 times in 50 trials
48:42
16:14
56:49
I hope this helps.
Answer:
Yes, r and h can be changed to produce same volume by;
Increasing "r" and decreasing "h" or by decreasing "r" and increasing "h".
Step-by-step explanation:
What the question is simply asking is if we can get same volume of a particular cylinder if we change the radius and height.
Now, volume of a cylinder is;
V = πr²h
Now, for the volume to remain the same, if we increase "r", it means we have to decrease "h", likewise, if we decrease "r", we now have to increase "h".

and the second one would probably i think 1500
