Answer:
1/30
Step-by-step explanation:
6 white marbles
5 red marbles
+ 19 marbles of other colors
-----------------------------------------------
30 marbles in total
First drawing:
p(white) = (number of white marbles)/(total number of marbles)
p(white) = 6/30 = 1/5
Second drawing:
Since the first marble is replaced, there are still 30 marbles in the bag.
p(red) = (number of red marbles)/(total number of marbles)
p(red) = 5/30 = 1/6
The two drawings are independent events, so the overall probability of the two events is the product of the individual probabilities.
p(white then red) = p(white) × p(red)
p(white then red) = 1/5 × 1/6
p(white then red) = 1/30
Answer:
The answer is C
Step-by-step explanation:
Answer:
1209 square meters
Step-by-step explanation:
2(1/2*16*15)+3(17*19)=1209
I assume you are asking how much time has passed
now, we can set up a proportion with this:
let x = time(in hours)
we cross multiply to get:
divide both sides by 50 to get:
hours
