Question

An experiment results in four possible out comes S,, S2, S3 & S4 with probabilities P1, P2, P3 & P4, respectively.
Which one of the following probability assignment is possbile.
[Assume S, S2 S3 Saare mutually exclusive)
(A) P, = 0.25, P2 = 0.35, P3 = 0.10, P4 = 0.05
(B) p. = 0.40, P2 = -0.20, P3 = 0.60, P4 = 0.20
(C) P, = 0.30, P2 = 0.60, P3 = 0.10, P4 = 0.10
(D) P, = 0.20, P2 = 0.30, P3 = 0.40, P4 = 0.10​

Answer 1

Answer:

As the experiment results in only these four possible outcomes, their total of probabilities should be equal to 11

From the given options, only p_1 = 0.20 ; p_2 = 0.30 ; p_3 = 0.40 ; p_4 = 0.10p

1

=0.20;p

2

=0.30;p

3

=0.40 ;p

4

=0.10 when added gives 11.

Answer 2

Answer:

Step-by-step explanation:

As the experiment results in only these four possible outcomes, their total of probabilities should be equal to 11

From the given options, only p_1 = 0.20 ; p_2 = 0.30 ; p_3 = 0.40 ; p_4 = 0.10p

1

=0.20;p

2

=0.30;p

3

=0.40 ;p

4

=0.10 when added gives 11.
