I did number 1 of the Second Experiment, but I don't know how to get question 2. Can you help me get A, B, C of question 2?

Second Experiment Now add up the number of heads for all the 50 trials. 1. Report the total number of heads. 2. 50 sets of 10 coin tosses, each, that means you ipped the coin 500 times. Theoretically the probability of heads at each individual toss is 1/2. A. What is the expected mean number of heads? B. What is the standard deviation? C. How many number of heads would be considered usuai/ordinary? Recall lesson from Binomial Distribution as well as the fact that ,u, 20' S ordinary values g p: | 20
