Answer:
If you assume a six sided die there are 3 odd numbers, 1,3, 5. And 6 total sides, so 3/6 = 1/2 or 50%.
A deck has 52 cards
There were are 13 clubs
There are 4 cards with "3" but one of them is a club, so there are 3.
P (club or 3) = (13 + 3) / 52 = 4/13
First convert 7.5 meters to 750cm, then use your formula A=1/2bh and pop it in your calculator: (1/2)(750)(6) and be sure to include cm as the unit of measurement in your final answer.
