Consider the experiment involving rolling a single die once.
What is P(even and Prime)?
I do not know how to start this can anyone help?
Which possibilities are both even and prime? Divide that by 6, the number of possibilities for a standard die.
Would they both be 1/2?
P(even and prime) means the probability of rolling a single number that is BOTH even and prime. You found P(even) and P(prime) separately.
so, because there are the same amount of even and odds wouldnt that make it a 1?
The only number that is both even and prime is 2. That is 1 possibility out of 6.
Oh.... I understand and see that now.
