A radio disc jockey has 8 songs on this upcoming hour's playlist: 3 are rock songs, 3 are reggae songs, and 2 are country songs.
sashaice [31]

Answer:

The answer is 9/64. Also #djgirlpower

Step-by-step explanation:

9/64 is the equivalent of 3/8 • 3/8, which is the probability of the dj picking a reggae song once, and then again. That is most likely the case, except if the song that is played is removed from the collection of not-yet-played songs. Otherwise, I’m pretty sure if that’s the case, it would be 3/8 •2/7. Hope this helped :)

Serjik [45]

Answer:

44 strawberries to 77 blueberries

Step-by-step explanation:

You must change the ration to 4:7 4 strawberries to 7 blueberries.

Then divide from the total to see how many you can have.

I am guessing that you have 77 of each. so that means you can have 44 strawberries to 77 blueberries.

At this point, you've used all your fruit! Time to go get moreE

Hope this helps!
