3) If you randomly select a card from a well-shuffled standard deck of 52 cards,

what is the probability that the card you select is a diamond or 10? (Your

answer must be in the form of a reduced fraction.)

4) If you randomly select a card from a Well shuffled standard deck of 52 cards,

6) A group of people was asked if they had run a red light in the last year. 466

responded "yes", and 364 responded "no".

23) A phenomenon is observed many, many times under identical conditions.

The proportion of times a particular event A occurs is recorded. This proportion represents:

• the distribution of the event A
• the correlation of the event A
• the variance of the event A
• the probability of the event A
