1. Step-by-step explanation:

   Given:–

   Cards numbered from 11 to 60 are kept in a box

   To find:–

   If a card is drawn at random from the box, find the probability that the number on the drawn card is (i) an odd number is divisible by 5.

   Solution:–

   Given that

   Cards numbered from 11 to 60 are kept in a box

   Numbers on the cards = 11,12,13,14,…,57,58,59,60.

   Number of cards = 60-11 +1 = 50

   Total number of all possible outcomes = 50

   Odd numbers = 11,13,15,17,…,57,59

   Odd numbers which are divisible by 5

   = 15,25,35,45,55

   Number of favourable outcomes = 5

   We know that

   Probability of an event P (E)

   = Number of favourable outcomes to E / Total number of all possible outcomes

   Probability of getting a card is an odd number which is divisible by 5

   = 5/50

   => 1/10

   Answer:–

   Probability of getting a card is an odd number which is divisible by 5 = 1/10

   Used formula:-

   Probability of an event P (E)

   = Number of favourable outcomes to E / Total number of all possible outcomes
