<h2>Answer:</h2>

The correct answer is:

        Probability of C = 0.1 ; Probability of D = 0.1

<h2>Step-by-step explanation:</h2>

We know that in any probability distribution with 4 events as:

        A,B,C and D.

The probability of all the events of the distribution sums up to 1.

i.e.

P(A)+P(B)+P(C)+P(D)=1

⇒ 0.5+0.3+P(C)+P(D)=1

⇒ 0.8+P(C)+P(D)=1

⇒ P(C)+P(D)=1-0.8

⇒ P(C)+P(D)=0.2

Also we are given that:

         P(C)=P(D)

This means that:

         2 P(C)=0.2

⇒   P(C)=0.1

Hence, we have that:

  Probability of C is 0.1 and Probability of D is 0.1

Find the oth term of the geometric sequence 7, 14, 28, ...
yaroslaw [1]

Answer:

The nth term of the geometric sequence 7, 14, 28, ... is:

a_n=7\cdot \:2^{n-1}

Step-by-step explanation:

Given the geometric sequence

7, 14, 28, ...

We know that a geometric sequence has a constant ratio 'r' and is defined by

a_n=a_1\cdot r^{n-1}

where a₁ is the first term and r is the common ratio

Computing the ratios of all the adjacent terms

\frac{14}{7}=2,\:\quad \frac{28}{14}=2

The ratio of all the adjacent terms is the same and equal to

r=2

now substituting r = 2 and a₁ = 7 in the nth term

a_n=a_1\cdot r^{n-1}

a_n=7\cdot \:2^{n-1}

Therefore, the nth term of the geometric sequence 7, 14, 28, ... is:

a_n=7\cdot \:2^{n-1}
