34 Exercises 187 EXAMPLE 7 GETTING FIVE HEARTS Find the probability of being dealt five bearts SOLUTION The sample is the same as in Example 5. The event consists of all pos- hands that include five hearts and no non-hearts This involves cltegories (hearts and non-hearts), so we will use the Fundamental Count- hinciple and multiply the number of ways of getting five hearts and the sible number of ways of getting no non-hearts There are...

A Review Learning Goal: Part D To understand the notation and basic quantities involved in nuclear physics. Which of the following choices lists a pair of isotopes? Nuclear physics borrows the symbols for elements from chemistry. However, knowing which element we are dealing with only tells us one of the numbers important to nuclear physics. When referring to a specific nucleus, we use the following notation: O s Fe. C and !AN He and Li 5N and 160 H and...
