Respuesta :

The probability that Kate chooses a two-digit number or a prime number randomly from the month of August is 7/31.

What is probability?

Probability of an event is the ratio of number of favorable outcome to the total number of outcome of that event.

Kate is randomly choosing a date in the month of August. This date must be a two-digit number or a prime number.

  • Total days in August month is 31.
  • Prime number data in this month is 11(2,3,5,7,11,13,17,19,23,29,31)
  • Two-digit number data in this month is 21(10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31).

The two digit prime numbers are 7(11,13,17,19,23,29,31). Thus, the probability is,

[tex]P=\dfrac{7}{31}[/tex]

Hence, the probability that Kate chooses a two-digit number or a prime number randomly from the month of August is 7/31.
