How many minmum number of times must he/she fire so that the probability of hitting the target at least once is more than 0.99?
Let the shooter fire n times.
Now, 
Now, P(hitting the target at least once) > 0.99 (given)
or 
...(1)
The minimum value of n to satisfy the inequality (1) is 4.
∴ the shooter must fire 4 times.
Show that X = 3 is the most likely outcome.
