For each Bernoulli process, find the expected number of successes: 1. Number of trials =10, Probability of success =0.6 2. Number of trials =210, Probability of success =1/10. 3. Number of trials =43, Probability of success =0.3. 4. Number of trials =23, Probability of failure =0.8. 5. Number of trials =59, Probability of failure =2/7.
