Question 3
Five friends stand from left to right: Anjali, Bernard, Chandra, Damini, Eshwar.
Anjali spells a ten-letter word correctly to Bernard, for example V-I-S-I-B-I-L-I-T-Y. Bernard whispers it to Chandra with one error: either substituting one letter (for example V-I-Q-I-B-I-L-I-T-Y) or omitting one letter (for example V-I-S-I-B-I-L-I-Y). Chandra makes one such error when telling Damini, and Damini makes one when telling Eshwar. If the original word is A-D-V-E-N-T-U-R-E-S, how many of these sequences could Eshwar hear?
- A-D-E-N-U-R
- A-D-D-E-N-T-U-R-E-S
- A-D-V-E-N-T-U-R-E
- A-V-E-N-G-E-R-S
- D-E-N-T-U-R-E
