The probability of a New York teenager owning a skateboard is 0.37, of owning a bicycle is 0.81 and of owning both is 0.36. If a New York teenager is chosen at random, what is the probability that the teenager owns a skateboard or a bicycle?

A recent study of a metropolitan area found that 31% of people owned a SUV, 74% of people surveyed owned a car, and 10% owned both. What's the probability that a randomly chosen person owned a SUV or a car?

If you roll one die, what is the probability of getting an even number or a multiple of 3? Are the events mutually exclusive or not?

 $P\left(A\right)=0.45$  and  $P\left(A\cap B\right)=0.2$  and  $P\left(A\cup B\right)=0.75$  Find  $P\left(B\right)$  .

 $P\left(A\right)=0.4$  and  $P\left(A\cap B\right)=0.15$  and  $P\left(A\cup B\right)=0.6$  Find  $P\left(B'\right)$  .

 $P\left(A\right)=\frac{1}{6};\ P\left(B\right)=\frac{1}{12};\$ 

 $P\left(A\cup B\right)=\frac{1}{4}$  

A and B are mutually exclusive.
