Answer:
AM = 4 units
Step-by-step explanation:
In any triangle
The distance from the vertex to the centroid is twice as long as the distance from the centroid to the midpoint.
The centroid divides the median in the ratio 2 : 1, that is
AM = × 12 = 4 units
The probability that 4 red cards and 9 black cards are dealt is 0.0735.
Let E be the event that 4 red cards and 9 black cards are dealt.
According to the given question.
Number of card hand that is dealt from a well-shuffled standard 52- card deck is 13
Total number of red cards in a well shuffled card deck = 26
Total number of black cards in a well shuffled card = 26
Now, the number of ways to dealt 13 cards =
Number of ways to dealt 9 black cards =
And, the number of ways to dealt 4 red cards =
As, we know that the probability of an event is calculated by taking the ratio of the favorable outcomes to the total number of outcomes.
Therefore, the the probability that 4 red cards and 9 black cards are dealt is given by
P(E) =
⇒ P(E) =
⇒ P(E) = 0.0735
Hence, the probability that 4 red cards and 9 black cards are dealt is 0.0735.
