What is expected value for this situation:

# of 8's if 50 cards are drawn WITH replacement.

b) Would this be a normal approximation?

### 1 Answer | Add Yours

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.
