Answer:
The probability of choosing two red cards would be 3/8
Step-by-step explanation:
The probability of choosing 1 red card is 10/16; the probability of choosing a second red card would then be 9/15.
P(2 red) = 10/16(9/15) = 90/240 = 3/8.
Answer:
The decimal number system in use today was first recorded in Indian mathematics.
Step-by-step explanation:
In the classical period of Indian mathematics (400 AD to 1200 AD), important contributions were made by scholars like Aryabhata, Brahmagupta, Bhaskara II, and Varāhamihira. The decimal number system in use today was first recorded in Indian mathematics.
Comment
If the least value of n is 4 that means that 4 is one of the numbers in whatever it is that you are describing. In other words n = 4 is part of your answer. If that is the case, the last two values are incorrect because 4 is not included in either one of them.
Discussion
So that means that you have to choose between one of the first 2. The key word is least. It means that the lowest possible value is 4. Nothing is lower.
When you write something like n ≤ 4 what you are saying is the n must be = to or less than 4. The arrow head points to the smallest number which, in this case, is n.
But the question says that the least number is 4. So the arrowhead must point towards the 4. This we have that n must be larger than 4.
Conditions
There are 2 conditions to this problem
n must be greater than 4
n can equal 4. It is the smallest number.

Answer:
he can still get a 5 but he is equally likely to get any other number 1 to 6
Step-by-step explanation:
he has a 1/6 chance of rolling 5 the first turn and it becomes more and more rare to roll lots of 5s in a row
1/6
1/36
1/216
etc
each time the denominator is multiplied by 6 because it is less likely he will roll a 5 so many times in a row
Answer:
length = 15 cm
Width = 12 cm
Step-by-step explanation:
Let width = w cm
Length = w + 3
Perimeter of rectangle = 54 cm
2 * (length + width) = 54
2 * (w+3 + w) = 54 {Add like terms}
2 *(2w + 3) = 54
2*2w + 2 * 3 = 54
4w + 6 = 54
Subtract 6 form both sides
4w = 54 - 6
4w = 48
Divide both sides by 4
w = 48/4
w = 12 cm
Length = 12 + 3= 15 cm
