Question
1) Consider a guinea pig. There are 3 possible coat colors for this species of guinea pig each with its own probability: Pr(orange) = 0.35, Pr(brown) = 0.6, and Pr(white) = 0.05. What is the probability of a guinea pig of this species being orange or white?
2) What is the probability of having a family composed of 8 male siblings?
3) Consider 4 species of plants in Point of Rocks Park where there are 140 White Pines, 189 Hackberries, 80 Pin Oaks, and 116 Tulip Poplars. What is the probability, and explain how you go about finding the probability, of randomly picking a Hackberry out of this park.
The probability is _____ . To get the probability, divide_____ by_____ .
4) Which are mutually exclusive events for a single draw from a deck of cards? Select all that apply.
red or black
jack or black
spade or diamond
ace or red
5) Check all that apply about probabilities and their attributes.
Probabilities can be = 1.0.
Probabilities can be = 0.0.
Probabilities can be > 1.0.
Probabilities can be < 1.0.
Probabilities can be > 0.0.
Pr(sample space) = 1.0
red or black
jack or black
spade or diamond
ace or red
Explanation / Answer
1) probability of a guinea pig of this species being orange or white=P(Orange)+P(Wite)=0.35+0.05 =0.40
2)
probability of having a family composed of 8 male siblings =P(all 8 are male)=(1/2)8 =0.0039
3)The probability is 0.36 To get the probability, divide 189 by 525
4)
red or black
spade or diamond
5)
option A,B, E and F are correct.
