Question

The probability of hitting a target in any shot is 0.2 .If 10 shots are fired then it's Mean =

and Standard Deviation​

Answer 1

Answer:

10×0.2=

$\frac{0.2}{10} = > 2$

Answer 2

The require answer is 0.865782272.

probability: Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one. Probability was introduced in mathematics to predict how likely events are to occur. The meaning of probability is basically the extent to which something is likely to happen. This is a basic theory of probability that is also used in probability distributions, where you learn the possibilities of outcomes for a random experiment. To find the probability of a single event occurring, we should first know the total number of possible outcomes.

The probability of hitting a target in any shot is 0.2.If 10 shot are fired, find the probability of hitting a target in any shot is 0.2.

The probability of not hitting in any shot is 1-0.2=0.8

Probability that the target will be hit at least twice = 1- hit once - hit never.

Probability of hit once = 0.2 *(0.8)⁰

Probability of Hit never = (0.8)^10

probability that the target will be hit at least twice =1 -0.2 *(0.8)⁰-(0.8)^10

     = 1-(0.8)⁰(0.2+0.8)

     = 1- (0.8)⁰

      = 0.865782272

Hence the require answer is 0.865782272.
