Question

cards numbered 1 to 12 are mixed in a beg. What is the probability that a randomly selected card would bear a prime number?​

Answer 1

Card Numbered From 1-12 in a bag.

Prime Numbers Between 1-12

=2,3,5,7,11

Total Prime Numbers=5

Total Outcomes=12

$\boxed{\mathtt{Probability=\frac{Favourable\: Outcomes}{Total\: Outcomes}}}$

$\boxed{\mathtt{P(prime\:number)=\frac{5}{12}}}$

Answer 2

Total number of cards=12
Let E be the event that the card drawn is prime number outcomes favorable to E are 5
P(E)=5/13
