Answer 2

Answer:

Concept:

Probability means event to occur. It is a branch of mathematics that deals with the random of a random event. The value is expressed from zero to one. Probability was introduced in mathematics to predict how likely events are to occur.

Find:

We find the probability

Given:

We given details

Step-by-step explanation:

1. When a die is thrown, the possible outcomes are 1, 2, 3, 4, 5, 6.

Number of possible outcomes = 6

Let E be the event of getting a prime number.

Outcomes favorable to E are 2, 3, 5.

Number of favourable outcomes = 3

P(E) = 3/6 = 1/2

Hence the probability of getting a prime number is 1/2.

2. Total no. of marbles=3+2+4=9

No. of black marbles=0

probability of getting a black marble= 0/9 = 0

3. For any event A, there exists another event A which shows the remaining elements of the sample space S.

A' denotes complementary event of A

A'= S - A

We know

Probability of an event + Probability of its complementary event = 1

It can be written as

Probability of its complementary event = 1 Probability of an event

=1-p

Therefore, the probability of its complementary event will be 1 - p.
