Answer:
2/10 * 2/10 = 1/25
Step-by-step explanation:
Suppose you have 10 marbles in a bag.
5 black , 2 pink and 3 blue
As if two pink marbles are selected then
for one pink marble
probability = event occurred / total outcomes
= 2/10
Similar probability for an other pink marbles
Probability for the drawing two pink marbles is
P = 2/10 * 2/10
= 1/25
Well, on every test I have at a school and I believe most schools do this. You need at leasr 80% to pass. But to pass you'd most likely need 80% or 70%. But if you get an 80% you'll be sure to pass! I hope this helps you!
Im pretty sure the answer is 20
1000*(1.06)^8. I'm lazy and don't want to type this into a calculator, but what you get out is the answer.
