StatisticsWhat is expected value for this situation: # of 8's if 50 cards are drawn WITH replacement. b) Would this be a normal approximation?

The 8's are drawn with replacement, therefore the probability of getting a 8 card is, p,
p = 4/52 = 1/13
The number of draws n is 50.
The mean = np = 50 x 1/13 = 3.84
np < 5,
Therefore we cant approximate this for a normal distribution.
