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
B C=0.1 and D=0.1
