<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

Answer:

The Value of a=\frac{15}{4}.

Step-by-step explanation:

We have Named the figure please find the attachment for your reference.

Given:

PR = y

QR = a

RS = b

PS = z

PQ = x

QS = 15

∠P = 90°

∠R = 90°

∠Q = 60°

∠S = 30°

We need to find the Value of 'a'.

Solution:

Now we know that:

In Δ PQS

∠P = 90°

∠S = 30°

Now we know that;

sin\ \theta = \frac{opposite\ side}{Hypotenuse}

sin \ S= \frac{PQ}{QS}

Substituting the given values we get;

sin\ 30\°=\frac{x}{15}

Now we know that;

sin\ 30\° = \frac12

So we can say that;

\frac{1}{2}=\frac{x}{15}\\\\x=\frac{15}{2}

Now In Triangle PQR.

∠R = 90°

∠Q = 60°

So we can say that;

Cos \theta = \frac{adjacent \ Side}{Hypotenuse}\\

Cos\ Q = \frac{QR}{PQ}

Substituting the given values we get;

cos 60\°= \frac{a}{x}

Now we know that;

cos 60\°= \frac12

x=\frac{15}{2}

So substituting the values we get;

\frac{1}{2}=\frac{a}{\frac{15}{2}}

By Using Cross Multiplication we get;

a= \frac{1}{2}\times\frac{15}{2}\\\\a=\frac{15}{4}

Hence The Value of a=\frac{15}{4}.
