Answer:
4/11
Step-by-step explanation:
multiples of 4 between 9 and 30 are: 12, 16, 20, 24, 28
multiples of 5 between 9 and 30 are: 10, 15, 20, 25
so there are a total of 8 numbers which satisfy the condition (20 is repeated twice, otherwise it was 9 in total)
total number of card = 30 - 9 + 1 = 22 (limits inclusive)
therefore the probability is 8/22 = 4/11
