Question

a box contains cards marked by number from 5 to 104 . a card is drawn at random find the probability that the card drawn card bears .a)a two digit prime number greater than 79. b) a number which leaves remainder 1 when divided by 6 .c)a composite number less than 43​

Answer 1

Step-by-step explanation:

total no. of cards=100

a)no. of two digit prime numbers from 5to104=21

probability=21/100

b)no. which leaves 1 when divided by 6=1

probability=1/100

c)no. of composite no. less than 43=28

probability=28/100=7/25

Hope it helps you

Answer 2

Answer:

(a) Total outcomes=100

Fav. outcomes=5

P(E) =5/100=1/20

(b) Total outcomes=100

Fav. outcomes=17

P(E) =17/100

(c) Total outcomes=100

Fav. outcomes27

P(E)=27/100
