This math class we did number of the day, probability test , and Mr. Isfeld taught us more about probability
This are the questions of the math test and their answers.

1. There is an equal probability of picking a red card or picking a black card from a full deck of 52 cards. Answer: true.
2. Using a six-sided die, the probability of rolling an even number is 1:3. Answer: false.
3. Using a six sided die the probability of rolling a 5 or a 6 is 1:2. Answer: false.
4. If there are fewer "favourable outcomes" the probability increases. Answer: false.
5. The formula for determining probability is = all outcomes over favourable outcomes Answer: false.
Multiple Choice
