Sam intends to roll a six sided cube 100 times. What is the probability model he can use to predict whether or not each roll wil

bekas [8.4K]

The outcomes of rolling fair six sided die is $\{1,2,3,4,5,6\}$ . The prime numbers in the above outcomes are $\{2,3,5\}$ . The probability of not rolling a prime number is $p=\frac{3}{6}= 0.5$ .

Each trial is independent.

In the given experiment of 100 trials, the binomial probability model can be used to predict the number of occurrence of non-prime numbers (X). The probability mass function is

$P(X=x)=C(100,x)p^x(1-p)^{100-x},x=0,1,2,3,...,100$ . Since $p=0.5,1-p=0.5$

$P(X=x)=C(100,x)0.5^x(0.5)^{100-x},x=0,1,2,3,...,100 \\ P(X=x)=C(100,x)(0.5)^{100},x=0,1,2,3,...,100$

First solve the triangle:
75° + 75° + x = 180°
150° + x = 180°
x = 180° - 150°
Therefore x = 30°
Then, use the geometrical property of vertically opposite angles.
Therefore. x° = 30°

notsponge [240]

Conditional: If p, then q

Converse: If q, then p

Inverse: If not p, then not q.

Contrapositive: If not q, then not p.

Blow, p is bold; <em>q is italic</em>; <u>not p is bold underline</u>; <u><em>not q is italic underline</em></u>.

<u><em>The truth value of each statement is bold, italic underline.</em></u>

Conditional: If a figure is a square, then <em>the figure is a quadrilateral</em>. <u><em>True</em></u>

Converse: If <em>a figure is quadrilateral</em>, then the figure is a square. <u><em>False</em></u>

Inverse: If <u>a figure is not a square</u>, then <u><em>the figure is not a quadrilateral</em></u>. <u><em>False</em></u>

Contrapositive: If <em>a figure is not a quadrilateral</em>, then the figure is not a square. <u><em>True</em></u>
