Step-by-step explanation:
Multiply the ratio numbers by 6 and you have
boys : girls = 2 : 3 = 12 : 18
There are 12 boys in the class.
Answer:
The number of white horses is 52
Step-by-step explanation:
Let
x ----> the number of black horses
y ----> the number of white horses
we know that
----> equation A

----> equation B
Substitute equation B in equation A and solve for y

therefore
The number of white horses is 52
Answer:
0.00069104 approximately.
Step-by-step explanation:
You must first calculate the probability of not taking a ball with the letter B.
It would be the sum of the probabilities of taking I, N, G and O.
The probability of getting the letter I would be 15/75, that is 1/5. The same would be for the letter N, G and O. Since the 4 probabilities are equal.
Therefore it would remain (1/5) * 4 = 4/5.
Then the probability of not drawing a letter B would be 4/5.
However, in the case that it does not go out for 26 balls and that the ball that was taken out is not taken into account. It would be the multiplication of all events, that is:
(60/75) * (59/74) * (58/73) * (57/72) * ... * (35/50)
The result would be 0.00069104 approximately.
Is there any more context to this question? Or can you use and answer. There are a lot of answers to this question, so long as x is not finite
Answer: 50000000 or 5^7 times more
