3/5= 6%

- anonymous

Thank you guys!

- anonymous

That's not the answer, we need to continue...

- anonymous

oh, ok. what else do we need to do?

- anonymous

oh its not sorry i thought it was nvm

- anonymous

Probability= Favorable Cases/Possible Cases= 2/4=...

- anonymous

50%

- anonymous

Good. Now..
60/100*50/100=...

- anonymous

0.3

- anonymous

Great!!!
0.3=30%

- anonymous

So is 30% the answer?

- anonymous

0.3 cause 100/60=0.6 and 100/50 = 0.5 wich is 0.3 move dicemal point and u get 30%

- anonymous

Yes! 30% is the requested probability!

- anonymous

One more question? how would i put that into complete sentences?

- anonymous

the percentage would be 30%.

- anonymous

go from that

- anonymous

Then describe the steps taken to reach that answer!!

- anonymous

yes! @jessicabraham2000

- anonymous

so wait how did we get 2/4

- anonymous

2/4= 50% is the Probability= Favorable Cases/Possible Cases

- anonymous

Ok thank you!

- anonymous

Your Welcome! Feel free to give me a medal and follow me!

- anonymous

The probability is 30%. I started of by using the fraction 3/5 which is 6% and then 2/4 which is 50%.
Then i multiplied 3/5 and 2/4 which was .3 and then i changed it to a percentage which is 30%

- anonymous

thats what i got.

- anonymous

i meant off not of btw

- anonymous

Looks good, but you might want to add why we used the fractions 2/4 and 3/5.
Add that it is Probability= Favorable Cases/Possible Cases

- anonymous

thank you so much.

- anonymous

Of Course!
