Answer:
23/40
Step-by-step explanation:
The multiples of 3 less than or equal to 40 are 3, 6, 9, 12, 15, 18, 21, 24, 27, 30, 33, 36, 39 (13 multiples).
The multiples of 4 less than or equal to 40 are 4, 8, 12, 16, 20, 24, 28, 32, 36, 40 (10 multiples).
P(E) = Total favourable outcomes/Total outcomes
= (13 + 10)/40
= 23 / 40
