Given :
Apa-bear weighs 250 lb.
Mama-bear weighs 50 pounds less than Papa-bear does.
Their 2 cubs weigh 80 pounds each.
To Find :
The total weight of the Bear family .
Solution :
Weight of mama bear = .
Total weight is the sum of all all weight .
Therefore , total weight of the Bear family is 610 lb .
Hence , this is the required solution .
There are 48639 ways for a lord to move from the bottom left to top right corner of the 8 by 8 chessboard
<h3>Further explanation</h3>The probability of an event is defined as the possibility of an event occurring against sample space.
Permutation is the number of ways to arrange objects.
Combination is the number of ways to select objects.
Let us tackle the problem.
This problem is similar to Pascal Triangle.
The Lord can move to the right or up in one way only.
We can put "1" in each box on the bottom and left to represent 1 possible movement.
To get the possibility of movement to another box, we will add the possibility of movement to the left, right, and diagonal squares as shown in Figure 1.
This process is repeated for the next box as shown in Figure 2.
Finally, after this process is repeated until the top right box, we get the results as shown in Figure 3.
There are 48639 ways for a lord to move from the bottom left to top right corner of the 8 by 8 chessboard.
