Question

What is the probability of coming a prime number on throwing a die​

Answer 1

Answer:

1/2

Step-by-step explanation:

P( getting a prime number on a die) = Number of favourable outcomes/total number of outcomes

= 3/6

= 1/2

Answer 2

Answer :- 1/2

Prime Numbers :-

Numbers which have no more than 2 factors, Which are 1 and the number itself.

So, On Throwing a dice, we get 6 possible outcomes.

Which are 1, 2, 3, 4, 5, 6

So, According to the question and definition of a prime number there are only 3 favourable outcomes ( i.e., 2, 3, 5 )

Note :- 1 is neither prime nor composite.

⇒ Probability of an Event = Number of favourable outcomes / Number of possible outcomes

⇒ P(E) = 3/6

⇒ P(E) = 1/2

So, we have an even chance of getting a prime number.

Hence, Probability = 1/2

Some Information :-

☛ Probability is the chance of occurrence of an event.

Probability of an Event = Number of Favourable outcomes / Number of possible outcomes

☛ Probability of an event can't be negative and more than 1, 0 ≤ P(E) ≤ 1
