Question

For each Bernoulli process, find the expected number of successes:

1) Number of trials =20, Probability of success =0.8

2) Number of trials =210, Probability of success =1/10

3) Number of trials =27, Probability of success =0.2

Step 1

From the given information it is needed to calculate the expected number of successes.

The formula for expected number of successes in n trial is:

Step 2

In case (1)

**n=20 and p=0.8**

so,

Step 3

In case (2)

**n=210 and p=0.1**

so...
