Answer:
40 CDs are by solo artists and 16 of the CDs are by female solo artists
Step-by-step explanation:
According to the question, Joshar has a collection of 1200 music CDs. He considers 1/6 of his collection rock music. Of the rock music CDs, 20% are by solo artists. Of the solo artists 2/5 are by female artists.
We are now asked to find many of the CDs are by solo artists and how many of the CDs are by female solo artists?
-----Joshar has 1200 music CD collection,
If 1/6 of his collection is rock music then the amount of rock music CD's with him is
1/6 × 1200
= 200
20% of the rock music CDs are by solo artists ie
20/100 × 200
= 40 CDs are by solo artists
Out of this 40 CD's, 2/5 of them are by female artists ie
2/5 × 40
= 16 are by female artists.
Five (5)
Using process of elimination, you know that it’s not 1 or 25.
Based on the lengths of the 12 and the 13, the most reasonable answer is 5.
Answer:1-5
Step-by-step explanation:Assuming the spinner is numbered 1–5 and has an equal chance of landing on any number, you have two independent probabilities, each 1 in 5.
Just multiply those: 1/5 * 1/5 = 1/25. You have a 4% chance of getting 2 twice.
Of course, if there’s anything special about spinning “2”, you’ll be keyed to watch for it after getting 2 the first time. Now there’s a 20% chance (1 in 5) you’ll spin it again, and you’ll be very excited that you got 2 twice in a row. Another way of saying that is that the probability of something that has already happened is 100%.
