1. We roll a fair five-sided die with numbers from 1 to 5. Assume observing 4 or 5 is success. Random variable of interest is the number of successes when we roll the die 10 times. a. What is the chance of having exactly one success (observing 4 or 5)? b. Find the expected number of successes. c What is the standard deviation of number of successes?
