The key to solving this problem lies in recognizing that the order of the frog's jumps (left or right) doesn't matter. It only concerns the number of times it jumps to the left and the number of times it jumps to the right. This makes it a classic case applicable to the Fibonacci sequence.

Solution

1. Total Jumps: We know the frog makes 7 jumps in total.
2. Left vs. Right Jumps: Let L represent the number of jumps to the left and R represent the number of jumps to the right. Since it reaches point C (bottom right corner), we have L + R = 7 (total jumps).
3. Fibonacci Connection: The number of ways to arrange L lefts and R rights is equivalent to calculating the number of combinations for choosing L items (left jumps) from 7 (total jumps). This is where the Fibonacci sequence comes in.

Fibonacci Formula

The number of combinations to choose L items from a set of N items can be calculated using the following formula:

nCr = N! / (L! * (N-L)!)

where:

• nCr represents the number of combinations.
• N is the total number of items (7 jumps in this case).
• L is the number of items to choose (number of left jumps).
• ! represents the factorial function (e.g., 5! = 5 * 4 * 3 * 2 * 1).

Applying the Formula

In our scenario, N = 7 (total jumps) and L represents the number of left jumps (which we want to find).

Case 1: All Left Jumps (L = 7, R = 0)

If the frog makes all 7 jumps to the left (L = 7), it won't reach point C (bottom right). This case isn't valid.

Case 2: 6 Left Jumps and 1 Right Jump (L = 6, R = 1)

Using the Fibonacci formula:

7C6 = 7! / (6! * (7 - 6)!) = 7! / (6! * 1!) = 7

This means there are 7 ways for the frog to make 6 left jumps and 1 right jump (satisfying L + R = 7 and reaching point C).

Case 3: 5 Left Jumps and 2 Right Jumps (L = 5, R = 2)

Following the same calculation:

7C5 = 7! / (5! * (7 - 5)!) = 7! / (5! * 2!) = 21

There are 21 ways for the frog to make 5 left jumps and 2 right jumps.

Case 4: 4 Left Jumps and 3 Right Jumps (L = 4, R = 3)

7C4 = 7! / (4! * (7 - 4)!) = 7! / (4! * 3!) = 35

There are 35 ways for the frog to make 4 left jumps and 3 right jumps.

Total Ways

Summing up the possibilities from valid cases:

Total Ways = 0 (Case 1) + 7 (Case 2) + 21 (Case 3) + 35 (Case 4) = 63

Therefore, there are 63 ways for the frog to reach point C in 7 jumps.
