Answer:

The probability that the card may be prime or even number is \frac{5}{6}

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

10, 11, 12,13,14,15,16,17,18,19,20 and 21

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 =\frac{4}{12}  

Probability of even number = \frac{6}{12}

Probability that the card may be prime or even number

= \frac{4}{12} +\frac{6}{12} = \frac{10}{12} = \frac{5}{6}.

Final answer:

Hence ,the probability that the card may be prime or even number is  \frac{5}{6}
