Thread: Number of combinations.

in the above figure how many possible ways are there to move in right direction

i am getting 4C1(3C2*1C1*(1/4)^3)+(3C1*1C1*1C1*(1/4)^3)

can yu help me in how to find the probabilty

Assuming we are standing at the origin? The probability of?

Hello, prasum!

Can you help me in how to find the probabilty?
