Answer:
(i) 4/5
(ii) 2/25
(iii) 7/50
Step-by-step explanation:
i) There are 10 numbers divisible by 5 between 1 and 50.
50 - 10 = 40
Therefore, probability = 40/50 = 4/5
ii) Prime numbers less than 10 would be 2, 3, 5, 7.
So, 4/50 = 2/25
iii) There are seven perfect squares between 1 and 50.
Therefore, probability = 7/50
