Given,

Number of times the die is thrown = 260

Number of times a prime number appeared on the upper face = 39

To find,

probability of getting a prime number

Solution,

Number of times the die is thrown = 260

Number of times a prime number appeared on the upper face = 39

probability of getting a prime number = Number of times a prime number appeared on the upper face/Number of times the die is thrown

= 39/260

= 3/20

So, the probability of getting a prime number is 3/20
