Question

(B) A box contains 50 cards bearing numbers from 1 to 50. If one card is drawn at random
from the box, find the probability that the number on card is
(2
© a multiple of 10
m) a two digit number​

Answer 1

Step-by-step explanation:

Total no of cards= 50

probability of getting 2= 1 card

P(2) = 1/50

multiple of 10= 10,20,30,40 and 50 = 5 cards

P(10×) = 5/50= 1/10

two digit number starts from 10 to 50

one digit cards are 1-9

so 2 digit cards= 50-9= 41

P(2digit)= 41/50
