15/20 |
| #5 |
A bag contains 20 pieces of candy. There are 8 grape, 7 cherry, 5 lemon. What is the probability of picking GRAPE OR CHERRY OR LEMON? (Bonus 10 points if you can write the fraction as a PERCENT also!) |
20/20 (BONUS 10 points if you also had: 100%) |
| Dice |
| #1 |
A dice is rolled once. Find the probability of rolling a 5. (Hint: the dice has 6 sides...) |
1/6 |
| #2 |
A dice is rolled once. Find the probability of rolling a 1 OR 2. (Hint: the dice has 6 sides...) |
2/6 |
| #3 |
A dice is rolled once. Find the probability of rolling a 3 or 4. (Hint: the dice has 6 sides...) |
2/6 |
| #4 |
A dice is rolled once. Find the probability of rolling a 1,2,3,4,5 or 6. (Hint: the dice has 6 sides...) |
6/6 (100%!) |
| #5 |
A dice is rolled once. Find the probability of rolling a 0. (Hint: the dice has 6 sides...) |
0/6 or 0% (Trick question....there are no 0's on a dice!) |
| Coin Toss |
| #1 |
You toss a fair coin in the air...what are the chances of getting heads? |
1/2 (50%!) |
| #2 |
You toss a fair coin in the air 100 times. What is the hypothetical probability of the coin landing on heads? (Hint: out of 100!) |
50/100 (50% of 100 is 50!) |
| #3 |
You toss a fair coin in the air 200 times. What is the hypothetical probability of the coin landing on heads? (Hint: out of 200!) |
100/200 (50% of 200 is 100!) |
| #4 |
You toss a coin in the air 100 times. It land on heads 80 times and on tails 20 times. Do you think this is a fair coin? Yes or No. Why? |
No, this is not a fair coin! The experimental probability (tossing the coin) and hypothetical probability should be close to the same! |
| #5 |
You toss a fair coin in the air 1,000 times. What is the hypothetical probability of the coin landing on heads? (Hint: out of 1,000!) |
500/1,000 (50% of 1,000 is 500!) |
| Stack of Cards |
| #1 |
A stack of 9 cards is places face down. They are the 9 letters in Wednesday: 'W''E''D'N''E'S''D''A''Y''.......What is the probability if picking a D? |
2/9 |
| #2 |
A stack of 9 cards is places face down. They are the 9 letters in Wednesday: 'W''E''D'N''E'S''D''A''Y''.......What is the probability if picking a E or D? |
4/9 |
| #3 |
A stack of 9 cards is places face down. They are the 9 letters in Wednesday: 'W''E''D'N''E'S''D''A''Y''.......What is the probability if picking a R? |
0/9 (Trick question, there are no R's in Wednesday!) |
| #4 |
A stack of 9 cards is places face down. They are the 9 letters in Wednesday: 'W''E''D'N''E'S''D''A''Y''.......What is the probability if picking a VOWEL? (Hint: aeiou) |
3/9 |
| #5 |
A stack of 9 cards is places face down. They are the 9 letters in Wednesday: 'W''E''D'N''E'S''D''A''Y''.......What is the probability if picking a W,E,D,N,S,A,or Y? |
9/9 (100%)! |
