Question

There are 100 flash cards labeled form 1 to 100 in a bag . When a card is drawn form the bag at random , what is the probability of getting ... (a) a card with prime number from possible outcomes ? (b) a card without prime number from possible out comes ?

Answer 1

Answer:

n(s)=100

n(E1) = 25

(a) for possible outcomes when a card is prime no b/w 1 to 100 P(E1) = 25/100 =1/4

(b) n(E2)

For possible outcomes when card is not a prime no

P( E2) = 75/100 = 3/4
