|dw:1440510204253:dw| One way to look at it is by the Venn Diagram. 30 out of 100 was purchased this year. 6 of those (from this year, namely 30) produced berries. How many of those from this year did not produce berries? What is the corresponding probability (out of the 30 from this year) that plants did not produce berries?
THanks for doing the step by step
Alternatively, use definition of conditional probability: P(no berries | from this year)=P(no berries and plants from this year)/P(plants from this year) =(24/100)/(30/100)
Probabilities are always between 0 and 1. If it goes outside, check and double check. Hope you put in the parentheses when you evaluated the expression above.
Yes, 0.8 is more like it. But do you understand how it works?
is this the right answer
|dw:1440511020660:dw| If we're given that the plants are from this year, the sample space is 30, so 24/30=0.8.
can you help me with one more
What is the probability that a randomly selected is fiction given that it is paperback write the anwser as a percent round to the nearest tenth if needed https://static.k12.com/eli/bb/1762/6_80414/2_62272_10_80682/d7736541de5f96149de46a4fddf3ce06b4c0217f/media/04afc71de70f3a3f496a2276dcfec494b5a2f201/mediaasset_1495877_1.jpg
write the probability as a percent round to the nearest tenth if needed
I'll leave that part to you! :)
Can you write 0.8 as a percentage and round to the nearest tenth if necessary?
ok, it's a new problem. Here you do the same as before, out of all the paper backs, how many are fiction?
Also, for next time, make a new post so others have a chance to help you!
