Answer:
The probability that the card may be prime or even number is
Step-by-step explanation:
Explanation:
Given , Cards numbered from 10 - 21
And one card is drawn randomly from the cards numbered from 10 to 21 .
Step 1:
Total number we have 12

Prime number are 11 , 13 ,17 , 19
Total no. of prime no. = 4
Even number numbers are 10 , 12 , 14 , 16 , 18 , and 20 .
Total number of even no. = 6
Probability of prime number =
Probability of even number =
Probability that the card may be prime or even number
= + = = .
Final answer:
Hence ,the probability that the card may be prime or even number is
