What is the probability showing the formula of choosing 4 red marbles out of a bag with 5 red marbles and 10 blue marbles?
Probability = number_of_ways_of_success/total_number_of_ways
If two events are independent, their probabilities are multiplied together, eg tossing a coin to get heads and throwing a 6 with a single [standard cube] die.
In this case, I guess you are choosing 4 marbles at random. This is the same as choosing one marble, then choosing the next WITHOUT replacing the first marble; each random choice of marble is independent of the previous in so far as the colour only depends upon what is left in the bag.
So the probability here is the product of the probability that the first marble is red, the next marble (without the first being replaced) is red and so on until 4 have been chosen:
Pr(1st red) = 5/15 (= 1/3) as there are 5 red marbles and 5+10=15 marbles in the bag
Pr(2nd red) = 4/14 (= 2/7) as there are now only 4 red and 4+10 = 14 marbles in the bag
Pr(3rd red) = 3/13 as there are now only 3 red marbles and 3+10 = 13 marbles in the bag
Pr(4th red) = 2/12 (= 1/6) as there are now 2 red marbles and 2+10 = 12 marbles in the bag.
Thus Pr(4 red) = Pr(1st red) × Pr(2nd red) × Pr(3rd red) × Pr(4th red)
→ Pr(4 red) = 1/3 × 2/7 × 3/13 × 1/6 = 1/273 ≈ 0.00366 ≈ 0.366 %

When tossing 5 coins simultaneously can you find the probability that at least 1 head is showing?
Probability not at least 1 head showing is when all 5 coins are tails: (1/2)5=1/32 Therefore probability at least 1 head is showing is 1-1/32=31/32

A pair of dice are rolled and the sum on their upturned faces is recorded What is the probability that the sum showing is 8 given that one die is showing a 5?
it depends on how many time you throw the dice. the increase number of your throw, the higher the probability to get 8 that one die is showing a 5. that what my opinion.
What is the probability of a number cube?
A number cube has six faces, so the probability of any one of them showing on a fair throw is 1 in 6, or about 0.1667.
When tossing 5 coins simultaneously what is the probability that at least 1 head is showing?
Probability of no heads = (0.5)^5 = 0.03125Probability of at least one head = 1 - probability of no heads = 1 - 0.03125 = 0.96875
This formula is a diagram showing the bonding between atoms?
The formula that is a diagram showing the bonding between atoms is called the structural formula. An example of structural formula would be for acetone OC(CH3)2.

That's one face out of six. So the probability is 1/6
