Explanation / Answer

21. Total cards in a deck = 52

Total hearts = 13

So,

P(Heart) = 13 / 52 = 1/4

Option A is correct.

22. P(Student cheated) = 840 / (840 + 1765) = 840 / 2605 = 168 / 521

Option B is correct.

23. P(AB-) = 1/100 = 0.01

Option A is correct,

24. Option D

25. 4*2*5 = 40

Option C

26. Option C

27. Option B
