What is the probability of getting a composite number on the first roll of a die and getting a prime number on the second roll?


Sagot :

for a composite number its 1/3 (2/6)

for  a prime number its 1/2

The probability of the composite number is 0.3333 and the probability of the prime number is 0.50.

What is probability?

Probability means possibility. It deals with the occurrence of a random event. The value of probability can only be from 0 to 1. Its basic meaning is something is likely to happen. It is the ratio of the favorable event to the total number of events.

The probability of getting a composite number on the first roll of a die and getting a prime number on the second roll will be

The total event will be

Total event = 6

There are three prime numbers {2, 3, 5}.

There are two composite numbers {4, 6}.

Then the probability of the composite number will be

[tex]\rm P = \dfrac{2}{6} = \dfrac{1}{3} = 0.3333[/tex]

Then the probability of the prime number will be

[tex]\rm P = \dfrac{3}{6} = \dfrac{1}{2} = 0.5[/tex]
