Answer:
0.8413 is the required probability.
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 4.00 centimeters
Standard Deviation, σ = 0.60 centimeters
Sample size, n = 16
We are given that the distribution of average diameter is a bell shaped distribution that is a normal distribution.
Formula:
Standard error due to sampling =
P(diameter of sample is more than 3.85 centimeter)
P(x > 3.85)
Calculation the value from standard normal z table, we have,
0.8413 is the probability that the the average diameter of sample of 16 sand dollars is more than 3.85 centimeters.
Answer:

(c)
(d)
Step-by-step explanation:
The letters in each tile are:
A, B, C, F, G, I, K, L, O, P, Q, T, V, W, X, Z
Total Number of tiles n(S)=16
(a)The probability of drawing any one of the letters
The Probability of drawing any one of the letters
(b)The probability of drawing either an "F" or "P" tile
P(Either an F or a P Tile) = P(drawing an F Tile )+P(drawing a P Tile)
(c)The probability of drawing a vowel
The Vowel Tiles are: A,I,O
Number of Vowels =3
(d)The probability of not drawing a "Q" tile
