Answer:
8 drops will take to fill the test tube.
Step-by-step explanation:
A volume of
millimeter test tube is produced by the dropper that Arwen uses.
Now, we are asked to calculate the number of drops it will take to fill the test tube.
Then,
of the millimeter test tube is equivalent to 1 drop.
So, 1 of the millimeter test tube will be equivalent to
drops.
Therefore, 8 drops will take to fill the test tube. (Answer)
Answer:
(a)1 out of 4.
(b)27%
(c)0.73 or 73%
Step-by-step explanation:
Tommy’s probability of winning is given as 0.27.
(a)Ratio Form

Therefore, the probability that Tommy will win is <u>1 out of 4.</u>
(b)Exact Percent Value
Multiply the probability by 100 to obtain the exact percent value.
0.27 X 100=27%
(c)Probability that Tommy will not win.
Probability that Tommy will win+Probability that Tommy will not win=1
0.27+Probability that Tommy will not win=1
Probability that Tommy will not win=1-0.27
Probability that Tommy will not win=0.73
