With one 6-sided die:
What is the probability of rolling an even number?
3/6 or 1/2
200
Using a normal 52-card deck:
What is the probability of drawing a number card?
(not including aces)
9 of each suit
9x4 = 36
36/52 = 9/13
200
1/3 x 1/3 = 1/9
200
Blue marble: 6/12 = 1/2
Coin: 1/2
1/2 x 1/2 = 1/4
400
With two 6-sided dice:
What is the probability of rolling an odd number
And
A number greater than 4?
3/6 x 2/6 = 1/2 x 1/3 = 1/6
I'll also take 6/36
400
Using a normal 52-card deck:
What is the probability of drawing a diamond card between 3 and 9? (not including 3 or 9)
diamond # between 3 and 9: 5/52
1/4 x 5/52 = 5/208
400
What is the probability of spinning a yellow space,
and then spinning a number greater than 4?
Yellow: 2/8 = 1/4
greater than 4: 4/8 = 1/2
1/4 x 1/2 = 1/8

OMG!! There are a bazillion animals on this farm!
There a 4 pigs, 8 cows, 5 ducks, 7 chickens, 2 ostriches, and 4 horses!
What are the chances that if they are all put in the same fenced area, and you are blindfolded, that you will touch a two-legged animal first?
Total animals: 30
# with 2 legs (ducks, chickens, ostriches): 14
14/30 = 7/15 = .47 = 47% chance!
(Yes, I rounded up!)
600
With one 12-sided die:
What is the probability of rolling a multiple of 2?
(2x1, 2x2, 2x3...)
6/12 or 1/2
600
Using a normal 52-card deck:
What is the probability of drawing an ace,
and then without putting it back,
drawing an odd # card?
Ace: 4/52 = 1/13
odd # card: 4 times 4 suits = 16 (3,5,7,9)
one less card: 16/51
1/13 x 16/51 = 16/663
600
What is the probability of landing on a red space,
and then landing on a white space?
red space: 2/16 = 1/8
white space: 8/16 = 1/2
1/8 x 1/2 = 1/16
600
What are the chances, that if you blindly pick 3 pieces of fruit, without putting them back, that you will pick a red piece, then a blue piece, the a green piece? (count the cherries separately)
Total fruit pieces: 13
Red: 6/13
Blue: 5/12
green: 2/11
6/13 x 5/12 x 2/11 = 60/1,716
which equals about a 3.5% chance!
(that you get the fruits in that order)
800
With one 20-sided dice:
What is the probability of rolling a number less than 15
And
Rolling a number divisible by 5?
14/20 x 4/20 = 7/10 x 1/5 = 7/50
or 52/400
800
Using a normal deck with 2 jokers:
What is the probability of drawing a joker,
and without putting any cards back,
drawing all heart face cards?
***Just write out the expression***
drawing a joker:
2/54 = 1/27
drawing all heart face cards:
3/53 --> 2/52 --> 1/51
1/27 x 3/53 x 1/26 x 1/51 = 3/1,897,506
(which reduces to a 1/632,502 chance!)
800
You land on $500, then $One MILLION$, and then land on Bankrupt!!!
What are the chances of that!?!?
$500: 6/24 = 1/4
One million $: 1/24
Bankrupt: 2/24 = 1/12
1/4 x 1/24 x 1/12 = 1/1,152
800
***Hint: convert the percent to a decimal***
Not rain on Monday: 90% = .9
Rain on Thursday: 30% = .3
9/10 x 3/10 = 27/100 = 27%
