If probability of hitting a target is `1/10`, Then number of shot required so that probability to hit target at least once is greater than `1/4`.

The probability of a man hitting a target is 1/2. How many xx must he fire so that the probability of hitting the target at least once is more than 90% .

The probability of a man hitting a target is 1/4. How many xx must he fire so that the probability of his hitting the target at lest once is greater than 2/3?

The probability that a shooter hits a target is (1)/(3). The minimum number of trials such that probability hitting the target atleast once is greater than (5)/(6) is equal to (a) 4 (b) 5 (c) 6 (d)

The probability of a shooter hitting a target is (3)/(4). How many minimum number of xx must he/she fire so that the probability of hitting the target at least once is more than 0.99?

If the probability of hitting a target by a shooter, in any shot is 1/3, then the minimum number of independent shots at the target required by him so that the probability of hitting the target at least once is greater than (5)/(6) is

The probability of hitting a target in any shot is 0.2 If 10 shorts are fired , find the probability that the target will be hit at least twice. [ Given: (0.8)^9= 0. 1342]

The probability of a man hitting a target 2 is He fires at the target K times (k a 5 given number). Then the minimum k so that the probability of hitting the target 7 at least once is more than 10 is

The probability of a bomb hitting a bridge is 1/2 and two direct hits are needed to destroy it. The least number of bombs required so that the probability of the bridge being destroyed is greater than 0.9, is :

The probability of hitting a target in any shot is 0.5 If 10 shorts are fired , find the probability that the target will be hit in an odd number of times .
