Sarah rolls a die twice. What is the probability that she rolls a 3 and then an even number?
vekshin1

Answer:

A) 1/12

Step-by-step explanation:

The sample space of rolling a die is { 1,2,3,4,5,6}

P (getting 3)= The number of "3"'s  in the sample space over the number of items in the sample space

P (getting a 3} = 1/6

P (getting  even)= The number of evens  in the sample space over the number of items in the sample space

P (getting an even} = 3/6= 1/2

Since these are independent events, we multiply the probabilities

P(3, even) = 1/6 * 1/2 = 1/12

1) idk I got none of your options
2)p=42,000÷(1+0.0225÷12)^(12×5)
P=37,535.04
3)PVAO=4900*12[(1/0.029)-(1/0.029*(1+0.029)^10]=504145.41..compare with 500000
So the answer is D
