Step-by-step explanation:
Python list of 6 numbers replace the second fourth and sixth number with the cube of the number
Given:
In a box cards numbers, 10 to 109 are mixed thoroughly. One card is drawn at random.
To Find:
Probability of getting a number that is a prime less than 40 is?
Solution:
Probability is defined as the outcome of getting a certain event out of all the possible events, the value of probability lies between 0 to 1 inclusive of ends. the formula for finding the probability of an event is,
So now in this situation, the total number of outcomes will be,
so total outcomes will be 100 and the outcomes when the number will be a prime number less than 40 will be,
prime numbers from 10 to 40 are 11,13,17,19,23,29,31,37, which is a total of 8 possible outcomes, now putting all the values in the formula given, which goes as,
Hence, the probability of getting a prime number less than 40 is 0.08.
