Answer:

Mean or expected value (μ ) = 1400

Step-by-step explanation:

Step(i):-

Given that the probability of success p = 0.7

Given number of trials n = 2000

Let 'X' be the random variable in binomial distribution

Now , we have to find the mean or expected value of the binomial distribution

 μ    = 2000× 0.7

  μ    = 1400
