Solution:
The possible outcomes are {13,14,15,…60}
Number of possible outcomes = 48
(i) Let E be the event of getting the number on the card is divisible by 5.
Outcomes favourable to E are {15,20,25,30,35,40,45,50,55,60}
Number of favourable outcomes = 10
P(E) = 10/48 = 5/24
Hence the probability of getting the number on the card is divisible by 5 is 5/24.
(ii) Let E be the event of getting the number on the card is a perfect square number.
Outcomes favourable to E are {16,25,36,49}
Number of favourable outcomes = 4
P(E) = 4/48 = 1/12
Hence the probability of getting the number on the card is a perfect square is 1/12.
