If repetition is not allowed in the 5 digit pin, then number of possible pins = 10C5 = 252
P(guessing it right in the first attempt) = 1/252
P(guessing it right in the second attempt) = 251/252 * 1/251 = 1/252
P(guessing it right in the second attempt) = 251/252 * 250/251 * 1/250 = 1/252
P(of guessing it right in 3 attempts .with different pin each time) = 1/252 + 1/252 + 1/252 = 3/252 = 1/84 = 0.0119
If repetition is allowed in the 5 digit pin, then number of possible pins = 10^5 = 100000
P(guessing it right in the first attempt) = 1/100000
P(guessing it right in the second attempt) = 99999/100000 * 1/99999 = 1/100000
P(guessing it right in the second attempt) = 99999/100000 * 99998/99999 * 1/99998 = 1/100000
P(of guessing it right in 3 attempts .with different pin each time) = 1/100000 + 1/100000 + 1/100000 = 3/100000 = 0.00003
Answer:
I'm not quite sure but I might
Answer:
It is important to fit your persuasive appeal to your audience's interest because they will not bother to listen to you or consider your idea if it does not relate to them. In the context of the similarity heuristics, the appeal should be something relatable and 'similar' in terms of their interests.
