The eight bones that make up the cranium.



frontal bone

occipital bone

parietal bone (there are two of these)

temporal bone (there are two of these)

ethmoid bone

sphenoid bone


frontal bone-The frontal bone is located in the forehead region. It is one of eight bones that form the cranium.

occipital bone-The occipital bone is located at the back of the skull and forms the base of the cranium. It is trapezoidal and curved in shape.

parietal bone (there are two of these)-One parietal bone is located on each side of the skull behind the frontal bone. The parietal bones basically form the roof and sides of the cranium.

temporal bone (there are two of these)-This bone is joined to the parietal bone on each side of the skull; it forms part of the base and sides of the cranium.

ethmoid bone-This bone is located in front of the sphenoid bone, at the top of the nose and in between the eye sockets. It consists of two masses linked by cribriform plates. The ethmoid bone also makes up portions of the nasal cavity walls, eye sockets, and cranial floor.

sphenoid bone-This bone helps to form the base of the cranium, sides of the skull, plus the sides and floors of the eye sockets. It consists of a middle section (which is the body of the bone), pterygoid processes, and wing-like sections that extend to each side of the skull. Each wing-like section on each side of the skull consists of two greater wings and two lesser wings. The sphenoid bone looks bat or butterfly-shaped.

When playing the card game Blackjack, multiple decks are used and reshuffled often so that the outcomes of the cards dealt are approximately independent. When a player receives two cards that are a combination of an ace and a face card, this is called a “natural blackjack” and automatically wins. A natural blackjack should occur in 4.5% of the rounds played. What is the probability that a player plays 20 rounds of Blackjack and gets two or more natural blackjacks?


The probability that a player plays 20 rounds of Blackjack and gets two or more natural blackjacks is 0.227.

Given the following data:

How to calculate the probability.

In this scenario, we can deduce that the number of natural Blackjacks (B) is in tandem with a binomial distribution with the following parameters:

  • Sample mean, n = 20.
  • Percentage, P = 4.5% = 0.045.

Mathematically, the probability that a player plays 20 rounds of Blackjack and gets two or more natural blackjacks is given by:

P(B ≥ 2) = 1 - P(B ≤ 1)

P(B ≥ 2) = 1- 0.773

P(B ≥ 2) = 0.227.

The correct answer is (C) or .227. The number of natural blackjacks (X) follows a binomial distribution with n=20, p=0.045.
