The probability of selecting two red marbles would be 1/19
The probability of picking a blue jelly bean is 10/12=0.833, since there are 10 blue and 12 jelly beans in total.
Each time the probability of picking blue is the same, since put back in the box whatever jelly bean we pick
P(blue, blue, blue) = P(blue) × P(blue) × P(blue) = 0.833×0.833×0.833=0.579
Answer: 0.579
The required probability of the coin landing tails up at least two times is 15/16.
Given that,
A fair coin is flipped seven times. what is the probability of the coin landing tails up at least two times is to be determined.
<h3>What is probability?</h3>
Probability can be defined as the ratio of favorable outcomes to the total number of events.
Here,
In the given question,
let's approach inverse operation,
The probability of all tails = 1 / 2^7 because there is only one way to flip these coins and get no heads.
The probability of getting 1 head = 7 /2^7
Adding both the probability = 8 / 2^7
Probability of the coin landing tails up at least two times = 1 - 8/2^7
= 1 - 8 / 128
= 120 / 128
= 15 / 16
Thus, the required probability of the coin landing tails up at least two times is 15/16.

Nine times the original volume
Step-by-step explanation:
Let the length, width and height of the rectangular prism be 'l' 'w' and 'h'.
The volume of the rectangular prism is given by,
V = W x l x h
The original volume of the rectangular prism is,
V = wlh
Here the length is 1.5 the original length
So, l = 1.5 x l = (1.5l)
And the with is doubled. So,
W = 2W
The height is tripled. So,
h = 3h
Volume of the new rectangular prism is,
V = (1.5l) (2w) (3h)
V = 9 wlh
We know that wlh is the original volume of the rectangular prism.
So the new volume is 9 times the original volume.
