A bag contains 7 red flowers and some yellow flowers.Probability of selecting a red flower is 7/15.What is the probability of selecting a yellow flower.
Plssssssssssssssssssssssssss answer my question fastttttttttttttttttttt
it's urgent
+9665 Let x be the total number of flowers.
7/x = 7/15
Obviously x = 15.
Number of yellow flowers = Total - Red = 15 - 7 = 8
Probability of selecting a yellow flower is (No. of yellow)/(Total)=8/15
+9665 That is complicated. A easier way to do......
No matter how you select the flowers, you must have selected a red flower or a yellow flower, so the probability of selecting a flower(red or yellow) is 1.
P(Red) + P(Yellow) = 1
I guess you wouldn't have found a turqoise coloured flower out from nowhere? <- That's not funny. You laugh because you sucks.
7/15 + P(Yellow) = 1
P(Yellow) = 1 - 7/15 = 8/15
Sorry I am a bit moody today so that I am not very nice. Even to my father and mother.
