An oil exploration firm is formed with enough capital to perform ten explorations. The probability of a particular exploration being successful is 0.1. Assume that the explorations are independent. Find the mean and variance of the number of successful explorations.

a) Mean = 1

b) Variance = 0.9      

Step-by-step explanation:

We are given the following in the question:

P(Success of exploration) = 0.1

Then the number of adults follows a binomial distribution, where

All the explorations are independent.

where n is the total number of observations, x is the number of success, p is the probability of success.

Here n = 10, p = 0.1

a) Mean number of successful explorations

b) Variance number of successful explorations

you first to choose the points and then move from then as the slope you have

the square root of 16 is 4.

4*4 = 16
