Answer:</h2>
The probability of A and B is:
<h2>
Step-by-step explanation:</h2>
We know that when two events: Event A and event B are independent then if P denote the probability of an event then Probability A and B is equal to the product of probability of the individual events.
i.e.
Here we have:
P(A) = 0.80 and P(B) = 0.10
Hence,
The amount of passwords possible is:
Since he only tries once for the first try we get:
Thus there is a:
Chance he will guess the password on his first try.
