Answer:
4
Step-by-step explanation:
You have to find the volume by dividing the diameter in half, which is 1, and then the volume is 4.19, and that rounds to 4.
<u>Answer:</u>
The correct answer option is P (both green) = 91 / 435
<u>Step-by-step explanation:</u>
We are given that in a jar containing 30 marbles, 10 are red, 6 are black and 14 are green.
Two marbles are drawn and the second one is drawn without returning the first marble and we are to find the probability of getting green marbles both time.
P (both green) =
= 91 / 435
The difference of a number P and one and four tenths is more than nine and seventy-eight hundredths.
P - 1.4 > 9.78
