Answer:
3/4
Explanation:
You can see that there are 4 cards with numbers 5, 6, 7 and 8 on them. They make the sample space. Total outcomes, n(S) = 4
Let the event E is picking a card not less than 6.
The outcomes of the event 'not less than 6' are 6, 7 and 8. So n(E) = 3
So, the required probability, P(not less than 6) = n(E) / n(S) = 3/4
